You sound alot like me... Besides the swinging. I am on Day 2 here after 8 years of not remembering a day of TOTAL sobriety. Did I get drunk every night no. A beer or two here... A case the next night so on and so forth. But always up bright and early for work. Mondays are the worst because tend to drink Hangovers away in the AM. But I was functioning. I just came to term this weekend when I drank WAYYY to much functioned but out of control. Tired of the black outs. Not one to make a fool of my self (usually) but I lost everything IE:Wallet, cell phone car keys and had no idea were they were. I am just taking this day by day see how my body reacts. I want to prove to my self that I CAN DO THIS. Good luck pal.
