Thanks for all the tips guys.

I'll try to take your advice on talking myself out of being paranoid and stuff, but to be honest, I really don't feel that paranoid at all when I'm high. The first time, I admit, I was kind of hesitant, but the second time when I puked, I didn't even feel sick or feel it coming at all. I just had my eyes closed and was trippin out about something (don't really remember what it was now) and it sorta just happened.

Do you think it would be possible to be allergic though, or is that just a myth?

P.S. One time somebody said they laced some hookah tobacco with weed (I didn't know about it at the time), and I was pretty trashed when I took hits from it so I didn't really feel anything. I didn't throw up or anything, but then again, I think the guy might be playin w/ me. I mean, is it even possible to put weed into a hookah in the first place?
