Propylhexedrine, but I only did it twice more, I don't think I could ever eat it again, or smell it without vomiting. It gave me the weirdest visual distortions ever.
Kratom, but I felt it at first, and then it made me SICK AS FUCK.
I think I said tobacco in this thread, fuck that stuff, haven't smoked a cig in a few months now, so FUCK YEAH.
Phenibut, I took it trying to chase some gabageric feeling, after the first time I got sick as fuck for like 10 hours.... so I tried it again, you know, expecting different results. stupid.
That's all I can really think of, oh I took darvocet once, and got scared shitless that I took too much tylenol and tried to force myself to vomit, but for some reason it killed my gag reflex, I've never been able to stick my finger down my throat without gagging, but with this shit I could have fisted my esophagus. Luckily I was fine.
Ranked by worse feeling (1 is worse)
1. Kratom (I thought i was dying for a day and a half)
2. Darvocet
3. Propylhexedrine
4. Phenibut
Tobacco never made me feel sick (except for a few gross nicotine buzzes) but it certainly damaged my health, 8 years of smoking....
