i recently got back from a rowdy weekend with my mates at V festival, lots of boozing and drugs, and inevitably, dares, i was dared by my mates to drink the kilogram of sand, dry sand, without a drink to wash it down with, thinking i was the big man after a few beers, i did it. my insides just feel so heavy and torn up, i feel like willy wonka has poked me in the eye with a pringle. what do i do to get rid of this terrible feeling???? please help, i honestly feel like im dying.
