I do this too, you're not alone. But then I remember how horrible I felt the mornings after a blackout. Wondering where the last three hours of the night went and what arguments I got into, who I hurt, how badly I abused the poor bartender for cutting me off. How I lost friends because I offended and embarrassed them one too many times. I just play the tape through--all the way to the next morning, the day after that, the day after that, etc. My life was horrible when I was drinking. Not getting out of bed for two days because of shame and embarrassment is far away from romantic!
Stay strong.
