I honestly have no idea. I’m assuming there’s a link there, too. There’s 7 billion different human makeups last I checked so there’s going to be some variety. Coffee definitely makes me sleepy sometimes, too. I’m also one of the unfortunate folks who have a stimulating effect from most alcohol.

There’s new buzz in the psych field that alcohol has a paradoxical effect on some people with specific genes whereby alcohol doesn’t have a sedative effect and, instead, has a stimulating effect.
