It could be some other cause too. A couple of years ago I started noticing that one or two beers would make me almost drunk and to feel terrible the next morning. I attributed it to aging (36) but I also noticed none of my friends had the same problem. Later, I was diagnosed with sleep apnea and after daily treatment now drinking a few beers is completely ok. I don't understand what the relationship between those two things are. I would have never imagined.
