Welcome to SR- I am sure you will get a lot of support and advice here
Alcohol did not bring me happiness or stable moods. As far as I am aware it is not a recommended medical treatment for anything. My addiction brought me plenty of grief. Only in retrospect do I recognise it diminished my capacity to deal with stress. Many on the boards are "high functioning" as well. I am professionally employed, and enjoy a comfortable lifestyle- I could however see where my drinking was taking me, and that was no where good. It was not until I started to cut back/moderate/'try' to quit that I slowly began to acknowledge the powerful and insidious nature of what I was dealing with.
I am sure you will get other responses soon.
