Drinking-healthy-liver question?

Hi, so I'm 22 years old and soon to be 23. I live a healthy life, I am in college and I cook most of my meals consisting of chicken/fish/red meat and fresh vegetables. I do not eat alot of junk foods and I never eat sweets. I try to work out 3 days a week and I do alot of daily walking during the school year. I do drink, whether it be beer, margaritas, bloody marys or whatever I feel like. I don't drink every single day but I would say I drink 2 to 3 days a week at most but sometimes I will drink 1 to 2 glasses of red wine with dinner. When I do drink I drink in between 2 and 6 drinks. The last time I was quote on quote wasted was over a month a go. I only get really really really drunk probably once or twice a month IF that. When I go on vacation and or in the summer I drink a little more because I like to try beers so some weeks I'll have 1 or 2 beers a day that's it. I'm asking if I am drinking too much or at risk for liver damage. Don't get me wrong i live in a college neighborhood with roommates and during the school year I see people wasted every night of the week, I try and not be one of them.
