teetotaled - abruptly forced into a life of teetotalism (complete abstinence from alcohol) due to health issues such as sudden allergic reactions or disease.
"I used to enjoy red wine with every dinner, until I was teetotaled in my mid 20's by a severe allergy."
"Some of the sportier frat boys and your average jocks are treetotalers, that is they are comfortable with corroding their livers binge drinking, but when someone offers to smoke them out, they react as if asked to sign their souls over to the devil."
Treetotalers may abstain for a number of reasons. Epilepsy, other psychoactive conditions or general Straightedge cultural adherence are two common conditions.
