The dreaded hangover is caused by a buildup of toxins, which the body tries to break down, said Dr. Edward Rosick, a physician and the chairperson of MSU’s Department of Family and Community Medicine in the College of Osteopathic Medicine. Alcohol also is a diuretic, which causes dehydration, he said. Rosick said there is no “hangover cure,” and pills advertised on the Internet might help but are by no means an easy fix.
“You need to go back and think about why do you feel like crap,” he said. “The number one cure is prevention — don’t drink so much.”
