I drank for 15 years to self medicate my anxiety and agoraphobia. Ive been sober almost 3 months and my anxiety is pretty damn bad. I was also a pretty avid weight lifter during my drinking days. That's also gone. I find lighter exercise works better for me (walking, lighter weights etc) Alcohol can definitely trigger anxiety. I got to the point that I had to smoke a little weed while drinking because the beer was starting to make my anxiety worse. Our bodies/minds will tell us whats wrong if we're willing to listen.
