For two days following a binge, I vomited profusely. It started out as a "normal" hangover and then turned into something else. I know a doc in my personal life... he did an abdominal exam and when he palpated that area under the ribcage, right side, it hurt so sickeningly bad I doubled up involuntarily. When it wasn't being palpated it throbbed with a kind of dull ache. This doc thought I had acute alcoholic hepatitis. I probably should have been in the hospital but got through it at home, started drinking again at the end of day 2.
Bad times. Glad to be sober today.
