I have cheated and drank wine one 2 occasions. I'm in R1P2SL, 5 days away from P3. On the first time I cheated with Syrah and drank the whole bottle. And yesterday I drank 2 glasses of Merlot and had sushi w/o rice and I was down 1.2#. My losses were very slow at the beginning compared to everyone else on the forum. So I altered my diet (no melba, breadstick, or fruit). Robbi has a good point that alcohol turns into sugar, but whats more important is your liver. Remember that your calories intake is very low and by adding alcohol your overworking your liver because there is not enough fat intake. (i'm a PA student)
Congrats on your losses! You should be very proud, just remember that doing this takes a toll on your other organs and the last thing you want is to become ill if your trying to be healthy. My suggestion if you must drink, have a full glass of red wine (has 0.5 to no sugar or carbs) once a week.
