You realize your sleeping patterns have squat zero to do with his drinking, right? In fact, he'd have far fewer sleeping problems after a few months of recovery...alcoholism is notorious for helping us fall asleep quickly (aka passing out) but then as the alcohol is metabolized our blood sugar drops and we wake up...for me it was 3:15 a.m. like clockwork.
It's a rationalization, but you know that.
Sending you a hug.
