I had a dual addiction of alcohol and Xanax. My doctor prescribed Xanax to help with sleep, and my growing dependance on it caught me totally by surprise ...never saw that coming. It's an awful, awful drug....Kicking both booze and Xanax was difficult for me......but I did it and so can you. I think you will find your brain and muscle power coming back, even if it does so slowly. Mine did. 31 days is awesome, but still early. Best suggestion I can give you is have patience with yourself.
