I don't really remember my acid trips, aside from remembering them as really really intense. If you're going to try psychedelics, I suggest doing mushrooms first because they are somewhat less intense. It's really up to you how you want to do it. I jumped right in the first time and ate an 1/8 oz. You could ease your way in by eating a couple caps to see if you like the feeling. It's really hard to describe the feeling, but if you smoke pot or cigarettes, you're probably going to want some handy. I just remember wanting to smoke like never before, and I rarely smoke either.
One mushroom trip, My roommate and I split a 1/2 oz, and we listened to the Allman Brothers - At Fillmore East like three times in a row. Good music is insane while tripping, and colors too. Tried playing some Super Mario Bros. on SNES, which was pretty awesome.
I apparently had a half hour conversation with a bush outside our dorm and wandered the campus for a while. If you have access to a car, I suggest giving your keys to someone who isn't going to be tripping with you. You'll probably want to go somewhere, and you really should not be driving under any circumstance.
As I said earlier, have some pot available if you smoke it, because coming down from an intense trip is the pits. For me, tripping is something that I'll do, and then have no desire to do again for like a month, but it really is a mind-opening experience.
There was something else I really thought was important, but I'm a bit high and I forgot. ****.
