So I guess my questions are:
#1: food yes or no?
#2: if yes before or after?
#3: I know adding stuff with fat like butter and cheese slows down how quickly my body turns carbs into sugar (I'm a type 2 diabetic with extremely high numbers on a regular basis) so would it be better to have cheese or butter with my bread to aide absorption? (I'm not totally alert atm so know the info is relative but can't figure out in which way)
#4: wine or hard cider yes or no?
#5: if yes just a little over my normal amount worth it?
#6: is the whole losing bowel control true and at what point? Urine too?
#7: can someone tell me how to set up prearranged texts? I want to setup ones that say stuff like "I'm having a crummy day and am going to sleep it off. Turning my phone off so it doesn't wake me" and other stuff I know will help keep the most suspicious loved one away. But I also want to send one to that same loved one a few days later telling them I've done it and to have police check so my loved one doesn't find me.
#8: any other related suggestions?
1) The main relevant effect food has is to slow the absorption of drugs via the GI tract, so this may be a concern, depending on what drugs are taken and how much. In going for a massive overdose, food shouldn't make a difference to fatality. However, some drugs do work differently on an empty stomach as opposed to a full one, so that might be worth looking into. I've been on medication that came with a "take with food" instruction, and in that case, it was because when taken on an empty stomach, they induced vomiting. So probably something to research with regards to specific medications that would be used.
2) Eating food after ingesting a fatal overdose seems rather pointless, so I'd do it before, if I were so inclined.
No experience with diabetes (#3) but if I were diabetic, I'd try to time an overdose with diabetic shock, just in case. I don't know if that's actually doable, though... maybe trying to do that would result in a diabetic coma before one could get around to swallowing an OD, I don't know, but it's something to think about.
4) Know your alcohol interactions. Alcohol is contraindicated with a great number of medications. With other depressant drugs, the risk is that alcohol can amplify the depressant effects and stop your breathing, with certain drugs it's more a matter of toxicity and long term damage to your organs (then again, I should have nuked my liver at least a decade ago if those warnings were accurate, so I take that with a grain of salt), and with some drugs, alcohol interferes with their mechanism of action and makes them ineffective (SSRIs and other anti-psychotics are examples of this). Finally, there are drugs, like MAOI antidepressants, which can have fatal interactions with alcohol unrelated to respiratory depression, but such drugs are generally not prescribed much any more.
Long answer short, check the information sheet and do some research on the relevant medications to determine if adding alcohol makes them more dangerous, less effective or doesn't matter.
6) It's true to an extent. When someone dies, they lose muscle control, so if you have a full bladder or a full bowel, that's coming out. If it's not to that point, it probably won't (without muscles to move food through the GI tract, it's not going to reach the unclenched sphincter, and without working kidneys, there won't be urine being deposited to the bladder). For whatever it's worth, a study done on victims of hanging executions found that a large majority did not soil or wet themselves... but some did.
7) There are a number of apps that allow you to schedule texts on a smartphone. I use Pulse SMS for my Android, I don't know if there's something similar for iPhones or other phone OSes, but Google should be able to tell you.
8) Anyone intending to OD with an oral ingestion should probably take an antiemetic first to prevent throwing up the drugs and potentially surviving an otherwise fatal dose. (A major reason drug overdoses have such a low fatality rate compared to other suicide methods.) Having the drugs in a puddle of vomit outside the body makes them ineffective. These days, worthwhile antiemetics are prescription-only in most countries, so that's a consideration. This is especially relevant if ingesting a large amount of alcohol. Ingesting a lot of alcohol does tend to activate one's vomit reflex.
Edit: LD50 is the dosage which is lethal for half the population, and due to ethical concerns, most are determined for lab animals, not humans. So someone wanting to induce a lethal reaction with more than 50% odds would want to take more than the LD50 value. For my money, a lot more, since I seem to have a high drug tolerance anyway, and am also not a mouse or lab rat.
