Yeah, it sounds like that's what's going on. It's just psychological though. The psychedelic state is a strange thing to say the least. That's very true what you say about not knowing that you "disliked" it, because while on it concepts of "like" and "dislike" can go out the window to some degree. The thing is 10 trips is definitely enough to cause the effect I'm describing. Not only have I done acid myself, but a lot of my friends take it on a regular basis.
