I had been abusing benzos and alcohol when I got clean. The dr prescribed beta blockers, a blood pressure med that can help with anxiety because as an addict it was insanity to allow me to continue to use habit forming meds, or to prescribe me a new one.
I had preexisting anxiety panic issues, which I had thought I was self medicating for with booze etc.
The beta blockers helped, they were not habit forming, I took them for a few months then stopped because I no longer needed them.
Anxiety is very common during early recovery. Work closely with your dr's, be deeply honest, and best to you. You can get sober, as horrible as it feels the anxiety won't kill you and it most likely will pass. I do NOT speak lightly of this. Anxiety is the worst thing I've had to deal with, panic attacks are very difficult to get through, but a solution that is likely to prevent both long term is the best one. If it's possible to avoid any new habit forming drugs I would suggest you do so.
