I was in a similar way - had to drink myself into unconsciousness and then the anxiety started again as soon as I woke up.
My growing need for alcohol was contributing mightily to that anxiety.
I did not think I could ever stop drinking, but I was wrong.
It wasn't easy but it was far from being as agonising as I convinced myself it would be.
In the end my fear of death trumped my fear of not drinking.
If you don't think you can do it yourself why not check out rehab as an option?
