welcome to SR.your drinking habits were just like mine.then I started drinking every day.
SR has helped me quit, 9 months now after many many failures,You CAN do this.It doesn't matter how many times you've tried and didn't quit.You can still quit now.
Do anything Friday night but don't drink, eat lots of food , drink water and soda, eat ice cream, watch a movie, read, go to the gym, walk, sleep early, stay glued to SR,anything but don't drink. Pour your booze away and don't have any in the house. I found in the early weeks it wasn't just physical cravings it was mental associations and habits.They do break in time though
