I have a lot of success WILDing after a night of drinking. Only if I've had a few drinks. Obviously, too many, and I'll zonk out until 3pm the next day.

For me, it has to do with the stimulant effects of alcohol. After a few hours of sleep, I wake up with my heart racing like crazy, and can't get back to sleep. I then have to get out of bed to calm down, drink some water, and relax. It is sort of like a forced WBTB.

I don't want to encourage anyone to drink more than they do anyways, but honestly, for me, it is very consistent and successful. I have the same success rate when I do a regular WBTB. I guess it just forces me to WBTB on a weekend.
