Welcome to SR. Admitting you want to stop and need help is a huge step in the right direction. Once hooked on this stuff,it is very difficult to quit. Doing it on your own makes it even harder. Getting help will make it easier.
I think the first thing to do is walk right into an AA hall like you own the place. Once through the door it gets easier. Every one there had to walk through the door for the first time also. They are there for the same reason.
Whether AA is for you or not will be your decision. For me,just being around other people with the same problem,trying to stay sober is what I needed.
Also if you are drinking a whole cup of whiskey in the morning to get started. I have a pretty good idea your wife knows exactly what is going on. Whiskey has a pretty loud aroma.
At any rate,keep on posting. There are a lot of people here that have been through this that can help.
