I knew a guy that drank a 24 of beer and a 750ml of whiskey every day and even had a bottle under his bed he would take huge gulps of just to get out of bed. He bought so much booze he won a several "best customer" T-shirts from his liquor store. He got sober sometime in his 50's and didn't have liver damage or at least none he ever told me about. Talk to your doctor if you are concerned.
