Speaking from experience here unfortunately but don't worry about your liver. You should be more concerned about wasting all that cash. I drank a lot during my first and only cycle. The result? I gained a good 10lbs of muscle but I also gained a good 15lbs in fat.
The reason I say don't worry about your liver is this but I'm sure people may be different in regards to how much alcohol their liver can take.
Back before my heart probs a month ago, I never took a break longer than 4 days in 4 years without drinking. When say drinking, I mean sharing a litre of liquol with my fiance. A lot of times, we were drinking 5,6, and even 7 nights a week. That's a lot of fucking alcohol.
Like I said, it's unfortunate that I speak from experience but really, you should worry more about all the money you'll be wasting.
