I know this is a very old post, but I just had to comment. If you have to take 10 hits to have a wonderful trip then the Acid that you're doing is very, very low dose or just crap to begin with. Back in the days of real acid (Sandoz, Orange Sunshine, Sugar Cube, Owsley) you could split one hit between 4 people and everyone would have a nice trip. If you ate the whole thing yourself you would have a VERY wonderful trip. In fact, there were a great many people that couldn't handle doing a full hit!!!
Acid was always great to me. It completely opened my mind. That was years ago in college though if I came across some that i knew was legit I would not hesitate to trip.
