I'll just copypasta what I posted in bigj75's Farewell Thread. Hopefully this is fine!
I just wanted to say that I tried the SN + DMSO (15g SN + 100 mL DMSO; I'm 18, male, and 150 lbs, athletic and healthy) method earlier on May 3 2019 and it was highly successful.
When preparing the solution of DMSO + SN, it definitely didn't completely dissolve. I used a teaspoon of SN (about 14.6 grams) plus 100 ml of DMSO. I also warmed up the DMSO by putting the container in a bath of warm water to help dissolve as much SN as possible. This step probably wasn't necessary, but I just wanted to see how much solute I could possibly dissolve.
I definitely felt nauseous immediately after drinking the SN + DMSO cocktail because it tasted and smelled disgusting. It felt pretty gross in my stomach too, but the nausea only became seriously uncomfortable after about 15-20 minutes. After that, it was bad enough that I couldn't really focus on doing anything other than just rocking back and forth in my bed, passing time until I would pass out. I got up and vomited at about 35-45 minutes after drinking the cocktail, which made me feel way more comfortable, but then I just stood there and passed out in my vomit a couple minutes after.
I ended up getting rescued because someone randomly entered my room probably around 20-30 minutes after I passed out. According to the doctor, I was the first case of SN poisoning in their 30+ year long career haha. He also approximated that I would've died if I received help ~30 minutes later, but take that with a grain of salt.
I definitely had acute methemoglobinemia though. My skin was all very purple and cold to the touch when I was found and it took me a few hours to return to normal in the ER with the help of methylene blue.
I'm better now and don't necessarily want to CTB, but I thought people would benefit from this info. Good luck guys, I hope you end up doing whatever brings you peace.
