i haven't done shrooms but i LOVE acid. threshold dosage is about 25 ug(micrograms), but you should prolly take 100-150 the first time. take one tab and when you start to feel it take another one if you think you can handle it. it takes a while to kick in, between 30-90 mins, sometimes up to 2 hours, so don't take too much thinking that its not working. its extremely hard to overdose, the ld50(lethal dose in 50% of subjects tested) in animals is around 12,000ug, but if you take too much your first time you prolly won't have a good time. i find that its very hard to have a bad trip, and i have never had one. i seriously don't understand why people have bad trips, because everything is so beautiful that you are just in awe of everything. having a bad trip is really the only danger, besides thinking you can fly and trying to jump out of a window, but thats why you have a sitter. the peak will last for about 5-6 hours, but you will feel the body-high for 8-12 hours and i don't know if this happens to everyone but i can't sleep for a while after.

as for personal experiences, i have stared into a pitcher of water for half an hour just saying how beautiful it was, i thought i was a barstool, and i came up with the designs for all my tattoos while trippin'. expect for the walls to breath and auras around lights.

Have fun
