Welcome back stephmadam.
Most of us ( me included ) reached a point when our drinking became uncontrollable, even though we were able to seemingly control it at one point in our lives. It's a natural progression of alcoholism and it only gets worseunfortunately, you can really never regain "control" anymore.
As carl said, cravings are merely thoughts...albeit powerful ones. You have a choice as to how you react to them...and not drinking is always an option. I see a large number of things that you "cannot" do during that time at night. What you most likely need to do is make a list of things you CAN do. A good start, which you've already made, is to come here on SR. It's quiet and you wont disturb anyone, and you'll be surrounded by literally hundreds of people who completely understand what you are going through. You could join the class of September thread or one of the many weekly/daily sober threads. You could also read about many of the self-paced sobriety plans like AVRT in the secular forums. There is a long list of books about sobriety and self help that you could obtain too.
