Question: how long do you have to drink before liver damage?
Answer: For cirrhosis to develop, men usually must drink more than about 3 ounces of alcohol a day for more than 10 years. Consuming 3 ounces a day involves drinking 6 cans of beer, 5 glasses of wine, or 6 shots of liquor. About half the men who drink more than 8 ounces of alcohol a day for 20 years develop cirrhosis.
