Yeah, I've gotten many a headache before. One of the worst was when I got my first hookah when I was still pretty new and I smoked a lot without eating or drinking anything for a long time. Then had to go outside and wash and wax two cars in 90+ degree weather. Hookah sickness mixed with heat exhaustion equals throwing up and dry heaving in the bathroom. I once had a summer counselor who always said "Hydrate or die."
