Welcome Globerover, I am sure you will find this site to be a very helpful site for trying to help you break the cycle of drinking too much. I myself am quit now almost 9 months, after a few unsuccessful attempts the previous couple years.
I want to point out to you a big benefit of quitting drinking that may not be that obvious up front. When i was drinking, my sleeping patterns were completely screwed up. Oftentimes, I was not falling asleep. Instead, i was "passsing out." The next day, I was sluggish and tired due to lack of proper sleep ( and on top of that, often hungover). Then on days when i did not drink, i found i couldnt sleep, because i had been dependent on booze to go to sleep.
Since I quit drinking, my sleeping patterns have returned to the way they are supposed to function. I fall asleep shortly after i get in bed (usually I read for 15 minutes). I get long, deep, uninterupted sleeps. These leave me refreshed and energized the following day, not to mention that fact I am not hungover!
So sleeping well has to be one of the biggest benefits I found since I quit drinking. I think this has drastically improved my overall well being. I found after I was quit a week or so, my sleeping patterns started to return to "normal."
I wish you all the best. For you or anyone starting the process, my advice to you is dont get thinking too far ahead. Handle it one day at a time. It gets easier wto not drink with each day that you dont drink. As the booze gets out of our system, your head starts to clear, and it gets easier to keep on track. At least that was my experience.
