Just keep at it letlife. Alcohol may help in the short term, but it won't help in the long run, you know that. And it certainly has side effects. Give the Prozac time, it takes up to a month for it to fully works, so don't give up on it after only a few days.
I also suggest vigorous daily exercise, healthy eating, and getting enough rest. Many people in recovery neglect this; they shouldn't because it does help.
