Anxiety, self-diagnosis, self-medication. Sounds just like my story.
I'll tell you what, them 30-60 beers a day aren't helping the anxiety ! Do you also suffer from depression ?
Constant headaches and panic attacks. I wake up every 2-3 hours in withdrawal (sweats, convulsions, nightmares, cramps, hallucinations). I puke bile *snip*quite often. I have many bruises. I bruise very easily.
That sounds just like me a little over 17 months ago....
All of these symptoms lessened or went away after I found recovery.
Like many here, I utilize AA.
I suggest you get to a place where you can be medically de-toxed. I'd also try and find in-patient treatment for alcoholism. 30 days at least.
