I also had the anxiety and panic attacks after I quit drinking.
Lasted about a year or so, but they were gradually decreasing in intensity.
Don't like pills - they are very addictive and I don't need more addiction in my life.
Sport helps me find a balance - running a few miles 3 times a week helps a lot.
Also, I use a herbal suplement which helps me calm down - try Valerian root (valeriana officinalis).
