Some time consuming alcohol itself can cause  you panic attack. I would like to advise you to stop alcohol first. You can take help of your psychiatrist for it. You just go for relaxation exrcise, yoga , meditation.  You can take clonazepam MD (mouth dissolving preparation ) 0.50 mgm during the next panic episode. Still it is frequent you should go for cognitive behavior thearapy from a psychologist. But before it other anxiety disorder needs to be ruled out. If still your symptoms not controlled you can be put on escitalopram 10 mgm , dose of which can be modified according to response. Hope it will serve your purpose for this consultation....good luck.
