hmmmm weirdmaybe u got something wrong... people are known to be more sensitive when on acid.. maybe you should have a doc run some tests or something... heard stories about ppl feeling tumors and stuff when they were tripping then after they went to the doctor and they had a tumor...i had euro acid once that gave me horrible kidney pains... but all american acid i never get anything like that... got my kidneys checked and eveyrthing is fine... maybe its my appendix instead.
