I don’t know if a citation would help—alcohol’s effect on sleep (and other things) is fairly personal. If you don’t already know, you’ll need to experiment and find out how it works for you.
In any case, alcohol is just the easiest of the hit-the-brain-below-the-cortex options. There are other alternatives, too, e.g. sex or stress.
Alcohol.
I don’t have a citation, but I’ve heard that alcohol will screw with your sleep. Might want to Google if you’re thinking about going that route.
