I have experienced panic disorder and anxiety and it was escalating with my alcohol abuse. Now that I have attempted sobriety(I have had a few relapses, but not to the degree I drank before) the anxiety comes roaring back. I wake in the middle of the night and feel awful, heart racing, etc... I also think it is in part a real effect of alcohol on th eheart rhythm and rate. Not good.
I feel much better sober, and you will too. Welcome and it does sound like you are in touch with your doctor. meds can take quite a bit of adjusting for anxiety treatment. Do talk to your doc and they can tweak and changes meds. I had one that caused me greater anxiety. Finally another had fewer side effects. You need to be followed.
