Can't tolerate alcohol any longer

I've never been much of a drinker. I'll have a beer or two with friends sometimes, and go binge drinking maybe three times a year, if that

Recently I've started having severe stomach issues after nights of drinking. Like, convulsions and constant vomiting and dizziness for up to 36 hours after intake.

I've been to the doctor's and they think it's alcohol induced gastritis. Means I can't really ever drink any more. It's recommended that I have at most 1 unit of alcohol, and only rarely.

Thought this was more of a chronic alcoholism problem, but apparently not. No more boozey nights for me
