yah i get huge headrushes when i'm sober, but it might be because i'm like really tall.. and i get really bad headrushes when i'm like laying down, but still kinda active, then get up real quick, thats when it hits. Some ppl say I like hit my head on a corner of a desk.. But i just kinda barley remember doing it.. kidna scarey cuz it likes happens to me alllll the time..
