Sorry you are suffering, Scott.
The things that have worked most to quell my anxiety in sobriety are exercise, meditation (if for only five or ten minutes each day), eating fairly regularly, limiting my caffeine to three cups per day, and getting enough sleep.
That sounds like a lot
However, whenever I let a few of those things slip, the effect is cumulative. I have to monitor myself regularly. I actually log these activities on an app. It seems tedious, but the alternative can put me in a state of mind conducive to drinking, and of course, that's my #1 no-no
