Anxiety and/or nausea seem to be a manifestation of some psychosomatic reaction to the release of subconcious material in some people. AFAIK, the only ones where true nausea is a factor are 2C-T-2, 2C-T-7 (possibly due to MAOI activity?), mescaline (from the sheer size of the dose) and of course 5-methoxylated tryptamines - 5-MeOAMT is the absolute worst IMO - due to their effect at the 5HT3 receptor.
There may be others that I've missed, but it's because I'm being a bit slow at the moment! :D

F&B your such a smartie
:D F&B- is mescalines effects on the dopamine system responsile for the nausea/vomiting?
