I've got this brain that cranks on full speed 24/7. Not that it's doing anything particularly useful, but I've never been able to shut it off. As I kid I was put to bed at 8 or 9, but never managed to sleep until midnight or later. When I became an adult and discovered alcohol it was a great relief. Finally a legal, easily available and effective way to turn my brain off.
I don't drink during the day and I don't like getting drunk. But I look at the four beers that put me to sleep every night as separate and distinct from whatever social drinking I do. I enjoy a beer with some evening meals. If I'm with friends who drink, I'll join in.
Please don't tell me that if I sobered up I'd be able to sleep. I was sober the first 20 years of my life and it didn't work!
