Hey Scared ,
For me to deal with being sober now i had to give up worrying about tomorrow or next week .
Alcohol will make you inTOIXCated for a few hours , then you will be hungover and sicker for maybe the following 20 , you will also be poorer and not actually delt with anything .
You will then also have the problem of trying to claw your way back to sobriety , never a nice experience IMHO .
I'm sorry you're in pain, maybe asking for help and advice of a Dr as to how to deal with it in a non-addictive way would be the solution ? Most normal people with back pain do that , not drink till they pass out .
Bestwishes, m
