Well, sorry, but I don't think you're a casual smoker. You smoke on any given day, and you want to smoke the next day, too. That's an addict.
You might need to give up the drinking for a while if it's a trigger for you. You could also try drinking in a different environment, say, a nonsmoking environment. But why torture yourself?
Can you not give up drinking for a month, maybe two, until you're secure enough in your quit? If not, sounds like maybe you have a couple addictions to battle.
There are plenty of ways to be social that don't involve bars and drinking.
Also, I don't think any of these meds/aids on the market will "stop" you from smoking. They're just aids. You have to want to quit. You also have to want to make any necessary lifestyle changes to help you in your quit.
Oh ... Chantix will more than likely curb any desire to drink, too. It certainly did for me. It might help you kill two birds with one stone on that one?
Best of luck
