Rupert,
My anxiety was horrific in the end.
The only way to quell it was...get drunk...but the booze caused it. It was a death spiral.
After i quit, it took months for it to go away. It is discouraging. But, I hung in there. Many need meds. I managed somehow w no meds. The meds are as addictive as booze w new issues...they tell me...
Get over the physical, then the mental shows through. Eat when you crave. Stay hydrated. Study your addiction. It is science, but faith and support help deal w the healing process.
It gets better everyday.
