When I look back I had two very definite problems - a long history of depression, and a concurrent but separate problem of alcoholism.
My experience of anti-ds when I was drinking is, not surprisingly, they didn't work that well, but I do credit them with saving my life at that period.
Prozac didn't curb my desire for booze or make me want to drink less, I'm afraid.
When I got sober I did a lot of 'work' on myself - some counselling patience and time was involved but gradually my depression resolved itself without medication.
I started on anti depressants again a few years back for nerve pain. I was 7 years or more sober then so there were no cravings to speak of anyway.
not sure my experience is that helpful, but there it is
