I was not drinking "quite" as heavily as you but I was drinking a LOT. I was not yet quite to the drinking at work... but wanted to on more than one occasion. Weekends and any day off? Heck, started in the morning and quit when I went to bed.
I'm little, too.
I quit cold turkey with Xanax for sleep. Loaded up on Vitamins, B6, 5-HTP and Holy Basil, drank a LOT of tea, and tried to eat well. The first four days were HARD HARD HARD and I relied heavily on God and this forum.
I am in Week Four..... and am finally feeling SO MUCH BETTER that I simply cannot believe I spent SO MUCH OF MY LIFE with that crap in my body. It's crazy.
I did it. You can, too. :-) Log in a LOT!!!! These people are great. :-) God Bless.
