Hope, (and Allsop)
Welcome to SR. I can certainly relate. But, all the exercise and healthy eating you do will not make you quit drinking. I may have used that to justify my drinking! (I ran and ate salad today - I deserve these bottles of cheap wine!)
For me, it took someone to wrench the glass out of my hand and make me quit. I really wanted to anyway but that was the kick in the butt I needed.
AA and similar organizations have helped many, many alcoholics recover. I'm a single Mom and it was not something I could work in very easily. SR members have given me support, advice, and a sense of not being alone.
Keep reading and posting.
