SkaterDude, First of all quitting is the best thing you can do for yourself. Once you have sufficient time not drinking most of the anxiety should disappear and sleep will also come in time. One day you will even have great dreams and awake feeling great. Google the 12 promises of AA, they are all true with enough time sober. Don't let anyone tell you different.
Secondly, quitting should help your relationships improve dramatically. If your wife is supportive, it may be best to tell her what you want to do with your drinking and ask for her help. But, YOU are the only one that can do it.
There are plenty of people here, at AA meetings and in your life who will help.
Be patient with yourself. Depending on how much you drink, how long you drank, and your individual body chemistry it will take some time to feel better. Stick with it.
There are people here who want to see you succeed! We are all in this together!
Stay with it!
