Vomitting isn't a given. I've taken 5-meo-amt on three different occasions, all estimated doses. One time I took way too much even and put myself in a world o insanity for a good 10 hours before i figured out what was going on. Never puked though. Gave a small dose to my girlfriend, who felt ill, but also never puked. Mom flushed the rest down the toilet when i made her give me her xanax, toilet never puked.

Don't tell people they're guaranteed to puke, suggestion is a powerful thing.
