I drink beer over about 9 hours, im not drinking 10 beers within a couple of hours. About 1 beer an hour, just over. Drinking 10 beers a day would be something to worry about, but not twice a week. And I did get my liver checked and it is fine. My liver has a nice rest 5 days a week. I'm also 180 lbs and 6ft so I probably need more than the average sized person to get drunk. And I do care about my health, probably far too much!
