I was prescribed xanax many years ago, when I was sober.
I have to say it was part of the problem, not the solution. I started drinking again after having been sober for 18 years...I started just months after being prescribed xanax.
Coincidence? I don't know. I do know I'll never use benzos again. They woke up that part of me that "takes something" to fix external or internal problems.
Exercise, healthy nutrition and eight hours sleep while practicing stress-reduction things like meditation and box breathing helps me just as much if not more.
