Hello! I can identify with everything you've said. You need to stay here and post and read and stay strong. I drank just like you and I'm day 7. Weekends are a huge trigger, just the mere mention that it's Friday or Saturday says to me it's drink time. I too wanted to quit, for months and I'd find myself in the liquor store and I would even say to myself "WHY AM I HERE?" I didn't want to be, I didn't want to buy that beer but I did and I'd drink my face off, be hungover, and continue it again the next day.
I've been going on my treadmill too this week. It makes me feel good and makes it easier to not drink. In fact I don't want to go on my treadmill this morning but as I type I'm sitting here in my work out clothes, just have to put my shoes on and GO. I will. I have to because it's one more piece in the foundation that encourages my sobriety.
Stay strong and you can do this. This is a great forum and it's helped me tremendously.
