I quit cold turkey about two years ago. I just didn't drink for a while until I had it beat. One thing I found is my mental state went from unhappy to happy almost right away after quitting. If I had known smoking was the cause of my depression I would have quit long ago. Its a horrible habit.
I think that is the key for me. Not drinking as much, It doesnt affect me when I drink in the house as I dont smoke there having a child and all. But when in the pub, oh dear. The advent of another child on the horizon though will mean my going outness is numbered and hence the opportunity to smoke. You are right though, its horrible.
