I drink occasionally-usually a glass or two of good wine. (I am not a mixed drink or beer person.)
You simply watch the portion, and count the calories just like you would in anything else. However, there are a few things that you should be careful of. For example, if you eat an average of 1400 calories a day, you don't want to "save up" your calories for booze on Friday night. You don't want to nibble like a bird all day, eating only 600-800 calories of food, so that you can have 4-5 drinks that evening. NOT good. Eating well, and saving 100-200 calories for a small drink or two is much better.
I have seen way too many Fitday pages where the daily intake was a salad early in the day, followed by pretzels and 5 beers that evening.
