I am not denying that for SOME it is peaceful, but this is far from the universal experience.
Please read the link I posted... there are real time posts and post-attempt experiences there of it being painful and gruesome.
It is important that people are aware of this possibility. There was a post from someone the other day who, believing that it would be a peaceful way to go, share his plan to CTB with SN in his bedroom which he shares with his little brother.
A couple of examples of non peaceful experiences:
"Moonicide: 25g in luke warm water drank through straw to help with taste, 48 hour regimen meto, 1000mg ibuprofen, 1000mg gabapentin, 800mg Tagamet, 8 hour fasting, throat and stomach burning afterward, pain rated 3.5/10, after 5 minutes needed to lay down, heart beating fast, feeling really warm but no pain, vomited twice, after 10 minutes breathing heavily, gasping for air, sounds like choking. After 10 minutes breathing slows down, leg spasms and grunting and loud groaning sounds. After 15 minutes vomits again, unconscious after 20 minutes. Witness did not think it was entirely peaceful.
Chat room: 25g, 72 hours regimen meto, 6 hour fast, ranitidine, tasted bad, burning throat, breathing slowly, 20 minutes after ingesting vomited violent, sounds indicated it became a very tough experience, horrible respiratory sounds, really distressing, don't know when she fell unconscious but we didn't talk anymore, 45 minutes after drinking she stopped breathing and dead (report from person who was on the telephone while someone took SN, could hear noises and groaning, did not think it was peaceful)."
