I got the antidepressant Lexapro before I quit drinking because I thought I was depressed... probably am some. But the benefit I found was the anti-anxiety aspect of Lexapro. I know that everyone is different, but cutting back on my anxiety has made it easier to quit drinking becasue I don't feel that panic to supress my feelings and zone out of life.
Of course it's not 100%... I'm not immune to my triggers, but it makes not drinking a bit better than I think it would be without Lexapro.
I did have the buzz effect when I started, and it did go away. And then I did get the tiredness in the afternoon after that (morning dose). To combat the tiredness, I just used old fashioned caffine! It helped me get through the grogginess and now I'm past all those side effects at 5 weeks.
best of luck, cant!
