something similar happened to me with mushrooms....the first 8 times i did them i had a great time....now every time i take them its just not the same......i keep thinking maybe its because i kind of set myself up for a bad trip when i first eat them by getting a little worried. anyways....i just recently went to a music festival and got this mushroom extract which gives you a different feeling....its so fun....maybe you should just try something else.....a whole lot of acid isnt too good for you anyway....
