Does being a lightweight drinker have anything to do with my liver?

Does the classification of a "lightweight" with regard to alcohol consumption imply anything about the liver? In particular, is there anything abnormal about feeling tipsy after only one beer (vital stats = 155 lbs., 6 ft.). I know my family has a history of liver problems and I have in the past drank to excess on many occasions. It has never taken much to become inebriated and now it takes even a little less. Should I be worried?


Where can I find support as an adult child of an alcoholic?

1) Are there any adult children of alcoholics groups on campus?

2) My father is an alcoholic and I've been told that I should stay away from drinking altogether. I'm a freshman this year and it seems like most of my friends always want to go to keg parties or hang out and drink. Sometimes I drink with them, but then I feel guilty and worried afterwards as I think about my dad. It's hard to avoid alcohol here, but I don't want to follow in my father's footsteps either. Any advice or support you can give would help. Thanks.
