Hi Suzie.
There are sister sites attached to this one for very good reason. They are related. Alcohol and anxiety do not go together, it is a depressant. Alcohol and meds do not go together. It is simple.
"you booze you lose". You can not help. Sympathy will only make it worse.
Alcohol works for panic in either of two ways and some times both. One is you just get blotto, so nothing registers or you get angry and transfer the panic to some one else by inappropriate venting. (some times with violence verbal or physical) Some would say how much do you want him. I have to ask how much he wants you. Not enough to stop the booze and get real help. Not enough to do CBT which is a proven cure. (you can't do it if you are drunk and can't think clear.)
Right now alcohol seems like a good friend to him and will become a better friend in the future. Even better than you are. Are you prepared to spend your life with a third person?
You can't fix this for him he has to do it himself. Even without alcohol in the equation a person with panic attacks or any form of excess anxiety has to do it themselves. And they have to want to.
It is not just alcohol. A lot of people run to drugs also to get away from the pain. Panic attacks are painful, but the thought of having one can be far more debilitating.
I would suggest you see a therapist. They can give you a lot more information in an hour than we can.
That said, and if you are still reading this, the program works. The forums work. Both are proven help. And we really are here for you even if I don't seem like it right now. There are others here more familiar with alcohol and anxiety they will tell you more than I can. You could also read the programs so you know what you are dealing with.
Davit.
