one of my friends claims to have the same problem as you, but when I see him munch the shrooms, he acts weird as fuck just like everyone else, he just says he didnt trip.

Are you sure you didn't feel the strange mush feeling in your innards and have racing thoughts or anything akin to that? Maybe you just didnt realize you where trippin. When I scarfed 6.8 grams of shrooms i was seeing 3-d green shapes everywhere. It was tight LoL
