I have tried b,c,e & i.
B only once and it was mixed with MDMA, so hard to say, but it was pleasant, made out with the hottest chick I've ever seen in my life, and danced all night to Sasha and Digweed. Everything looked as though it was made out of melting marshmellows. It did however make me vomit, but that was most likely from the MDMA.
E, has been a very profound psychedelic teacher, like many others have said, it's a very deep and introspective tool. Like most will say, it's not much fun but what you Learn about yourself and life has had long lasting positive effects. It has a rather harsh comeup consisting of nausea and muscle cramps, but they pass and I've found invaluable relief from preloading with lemon essential oil. I'll let you do the research on that as that subject is a post on it own. This is my favorite of the 2c series and quite possibly my favorite psychedelic compound.
C I have tried only once and had a really weird reaction. Made me feel really sick and confused, vomited every 30 mins, couldn't keep water down, shakey, dirty visuals that just didn't seem right. Was curled up in a ball in bed waiting for the dirty psychedelic psychosis to wear off, this was on 30mg. I feel like it was some weird annomolie with my body chemistry and the chloro just doesn't do well with me, but I wouldn't recommend it and I wouldn't ever do it again.
I, is the funniest one of the bunch. Never have I seen a drug have such variable effects. Sometimes it's laughter, sometimes it's visual, sometimes it's a rolling sensation, some times deep, sometimes shallow, no two trips on it for me have been the same, and all from the same batch. One time I tripped on it I swore it to be the most colorfull hallucinogen ever, no so much distortions, but everything was changing colors constantly, it's never been the same since, even on higher dosages. The last trip I had on it I became very nauseous, and confused. I couldn't talk, I felt as though I was on some kind of fucked up speed rather than a psychedelic. Came down to an anxious state of being, my mind would not shut off. I got one of the gnarliest migranes I've ever had in my life. I just don't know what to think about this one, it's been fun but it's also been terrible. Oh one more thing I feel I should mention is that I have found less to be more with this stuff, my fav dose is 16-17mg, any more and the effects Arnt all that increased but the tweaked feeling does.
Hope this helps someone
