Uh, yeah.

I've learned to lay of alcohol, even a bit. Finally realized that I went from feeling blue to almost suicidal when I had a drink.

Good for you to notice that it has that effect on you. But even if it doesn't have that effect on anyone else, if it does on you, that's all that matters.

And it doesn't even matter why. Just keep that connection in your head. "Gee, booze makes me feel bad".
