Are you seeing a doctor who specializes in psychiatric disorders? There are many different drugs to try. I know some of them take a few weeks to stabilize in your system. Don't give up and drink, that will set you back and you may never find a solution. There is a solution - I know I searched for years, and we are all still learning. The obsessive thoughts - have you tried Cognitive Behavior Therapy?
Keep trying different things - exercise, healthy food. Are you currently working the steps in AA? That is the meat of the program and where you will find the most relief.
