I just tried breathing in nitrogen for almost a minute. My ears were ringing like crazy, sounds like when grenades go off in battlefield. How close am I to passing out? Why is it so difficult to lose consciousness. Like how many minutes are required, that's why I want to do it when asleep. I'm in the process of setting up my sleep setup with a timer. If I inhale the gas while sleeping with zolpidem sleeping pills, could I possibly wake up and survival instinct kicks in? What can I use to fully sedate me so when I'm unconscious prior, when the timer runs out and the nitrogen gas flows into the exit bag, there is no way I can fight back. I want to die ASAP.

@SadCryingBunny

Do you have a pulse ox? It should drop precipitously in the first 20 seconds, after which unconsciousness should set in. But before you go unconscious, your pulse ox should decrease. This is an indication that your set up is correct.

I'll buy one. What level does it need to drop to for conscious to be lost? I'm testing via breathing from hose in exit bag or sometimes directly from hose while holding nose shut. After 30 seconds or so the sensation becomes very intense and I can't tell whether I will pass out or not, does it just suddenly happen? I don't want to damage myself accidentally. I'm just testing so I'm prepared on the day I ctb

I'm not sure what level it has to be for consciousness to be lost, but you should see it decreasing during your tests. If you do not, I'd say oxygen from surrounding is getting in.

that's weird. nitrogen is a silent killer, it shouldn't cause air hunger or any symptoms at all. are you sure it's pure nitrogen? what form is it, liquid or gas and is it a tank?

When breathing nitrogen, you lose consciousness gradually; it is impossible to predict the exact moment before losing consciousness. I conducted an experiment, and I lost consciousness unexpectedly within 15 seconds (using an SCBA mask); the only warning sign was that my vision began to darken around the edges. Be careful with such experiments so you don't end up disabled. I also experienced convulsions.

If restrained by the legs and hands tied under one leg thigh. During the convulsions will I move a lot? How long will the process be? I want to be dead and over with.

Did you breath nitrogen in an enclosed environment? I think that's why pph book mentioned exit bag, so the bag is full of nitrogen, no oxygen left. If you unleash the gas in a room, and breathe in nitrogen, i don't think you'll lose consciousness because there's still more oxygen in the room than nitrogen. Correct me if i'm wrong here anyone?

Is your ear still ringing?

Correct.
The most important way to succeed with this method is to understand HOW and WHY it works.
The more you read about it, the better.
Nitrogen is NOT poisonous!
I repeat,
nitrogen is NOT poisonous!
It doesn't kill you by poisoning you.
The nitrogen does not kill you.
It is the lack of oxygen that kills you.
The nitrogen causes you to pass out so that you don't notice the lack of oxygen.
The purpose of the exit bag with gas flowing into it is to create an OXYGEN FREE atmosphere around your head.
You first push all the air out of the bag, then the gas starts to flow in.
You want to know if the small bag can be swapped for a car or small room.
Are you seeing yet why that can't work, since you now understand the gas is not poison?
All of the air would need to be somehow removed from the room for that to be effective.
No such air removing invention exists.
Releasing some nitrogen into a car or room filled with air would have no way to do anything to you. All it would do is waste perfectly good nitrogen.

SadCryingBunny has issues with nitrogen that are very atypical, I wouldn't let them worry you too much.

I get that he didn't follow the procedure, but what was physiologically happening that made him still conscious with all these symptoms? I imagine it's like the same with Kenneth Smith. Is it because you will feel those symptoms regardless, but if you black out quickly you won't be aware of it? I saw some of the videos he posted, but I'm not sure if he used a flowmeter/regulator in them. I think the bag wasn't full of Nitrogen as well. I saw that bag kept inflating and deflating.

Right. You're on to something. It's a very technique dependent method, and the steps aren't being followed. When everything is done right and everything goes right, consciousness should be lost in about 15 seconds, or two deep breaths. It's not going to be the right method for everyone because you need to be able to sit back and allow it to do what it does.

No way consciousness can be lost in 2 deep breaths. I've bloody tried it with a oximeter and was still conscious at 49% blood oxygen levels. I also figured out what was causing me the exploding head feeling and rapid heart rate. MINOXIDIL. I was taking it topically 3x a week at a very low dose for hairloss. I stopped completely and am able to tolerate the nitrogen much better. I'm just getting ready to die in my room although I do not want to be autopsied. So that's why I am holding off. I've been talking to higher power/God lately and telling him I'm really sad and I just want to go to sleep and die. I believe in a higher power with 100% certainty because I do not believe the human eye could have evolved with out a guided intelligence nor creatures having wings and flying without a designer. This is where I would like to die, in my cozy wardrobe.

What current sensations are you getting now from the Nitrogen? Are you using a flowmeter or regulator?

Breathing directly from the gas transfer or silicone hose. If I do testing from exit bag each time it will deplete the tank quickly and it's $90 a fill and I don't want to draw any suspicion. Sensation are much more natural if that makes sense. Less intensity of body spasming sooner, less higher heat rate. Overall a much more tolerable experience since lowering topical minoxidil and RU58841 dosage. I hope I can ctb now but the autopsy is what stops me.

I'm concerned about doing the testing too since the amount would run out. If I do it in my home country, I could get 2 cbm, but that would take some long-term planning since I live with my folks and I have to move out. If I do it in my second home country, I would probably have to settle with 20 cuft, but that would take some manouvering. I wish I could get the Nitrogen gas. If I could get it now, I'm good to go. The only obstacles I have are not rousing suspicion and would be doing the actual testing when I get it. Even with partial hanging I had to do some testing, I can't imagine with Nitrogen I wouldn't.

can I ask something? what regulator are you using? that's for me, because i am having problems with the regulator.

About you, the book says following the instructions of the protocol is key, specially this:

hyperventillation during two minutes, then putting the bag over your head and taking two deep breaths, and you should loose consciousness at that point... I hope i was helpful. Sorry for my english.

I just want to put the bag and flush in nitrogen at a high flow rate and just breath until I fall asleep. Otherwise start breathing nitrogen when the oxygen supply coming from the hose runs out and die when I am already in my sleep.

For the exit bag, hole on the bottom, regulator at 15LPM, stay seated not prone so the exit bag works properly. With the hose you still intake oxygen since oxygen is basically present everywhere. The idea with N2 is that it is lighter than air and pushes air out of the bag through the bottom hole. Once in place it takes one to three deep breaths to lower you blood oxygen under 4%, making you pass out.

As for the ear ringing, it might be due to your ear canal not resisting the pressure on the hose in or close to your mouth/nose.

Edit : If in America with an Argon regulator, I think the gas should be around 27 cubic feet for 15 LPM

Blood oxygen was at 49% and I still didn't pass out after 90 seconds of breathing slowly. At what percentage do I start to get close to passing out?

It's too little, I like a higher flow rate to make sure any co build up is flushed as it's that urge to breath that give me a headache and activates the urge to breath/suffocation feeling.

If you are using an SPO2 scale for blood oxy you should have passed out at <60%. If you have a headache and air hunger the CO2 is not evacuating properly from your bag. Air hunger and headaches are only due to CO2, not O2 deficiency.

He knows, but is only willing to do it his own way, refusing to accept that it only works when protocol is followed.

The video clearly shows me wearing a pulse oximeter on my finger. It showed me at the last moment I was at 49%. I still did not feel anywhere near passing out but was getting somewhat close.

What can I use to fully sedate me so when I'm unconscious prior, when the timer runs out and the nitrogen gas flows into the exit bag, there is no way I can fight back. I want to die ASAP.
So, I did my own testing. @DeathSweetDeath , like @SadCryingBunny, I heard a crazy ringing sound as well along with a sensation of wanting to spit/puke and feeling dizzy. That said, I felt like I was on the verge of passing out, as I knocked over my tank without realizing it in the moment. I think that the point is you pass out quickly, so these sensations wouldn't even be registered or experienced as you would lose consciousness quickly.

I just did some testing because I wasn't ready to go and wanted to dip my toes first so to speak. Also, I thought the process would be gradual as in with this method it's a gradual drift to slumber, so I thought there wouldn't be any harm cause I would just take the exit bag off if I felt my vision fading.

What I did was put on the exit bag and inflated it at 15 LPM (apparently 17 LPM on the Argon flowmeter/regulator is equivalent to 15 LPM based on what I'm reading on SaSu) without inflating the exit bag on top of my head and hyperventilating first. I didn't expect anything much to happen, but it happened really fast. Like I said, I experienced all of the above sensations. I bet that if I inflated the exit bag on top of my head and hyperventilated before pulling the exit bag down, I would've passed out and CTB-ed.

@SadCryingBunny , I think that if you do everything quick enough, you would bypass this process, as you would instantly lose consciousness. Actually, now, I don't think it's 100% painless, but it's painless in the sense that if you do it quickly enough it won't be if that makes sense. In other words, it's painful if you're conscious.

You are saying there was some pain, was there pain when getting near unconsciousness? Could maybe an overdose on zolpidem sleeping pill make the passing out process less aware of pain? I tried nitrogen the other week and here is my testing video of me just breathing through the hose. My blood oxygen levels dropped to 49% and started to feel I was getting somewhat close to passing out. My ears this time did not ring nor did I get the needles numb feeling on my face. I think my body has gotten used to this gas from so much testing or maybe these sides will appear once I am near unconscious.
