Some people drink like fish and never get it, some drink a little over years and get it. There are so many factors involved it is not quantifiable. If you consume excessive( which you are ) amounts eventually over time you will In fact damage your liver, wether you end up with cirrhosis, is something no one can answer. Besides why play with fire, knowing eventually you could get burned. Try other ways to de stress. Alcohol being addictive will only make your life and relationships more difficult as you become dependent.
