I was just going to post this as well. I went for a cholesterol check and unknown to me they also checked my liver function (the b*stards).
So, my
alanine aminotransferase is at 66, should be under 35
I have been drinking about 40 units a week now for 3 years--and feeling fine with it--but my liver obviously isn't (the wimp!)
Anyhoo...I'm not touching a drop for 36.5 days from every new years eve now

...and I'm going to try to cut down my consumption during the rest of the year as well
The thing is, I feel fine on the amount I've been drinking, very rarely drunk, rarely even slightly tipsy. Liver damage can sneak up on you slowly with no ill effects. Take care!
