Alcohol Makes Me...Sleepy?

I was at my bf's cousin's graduation party and there was alcohol being served. My bf drank a couple of beers and I only had one drink since I agreed to be the designated driver and I have to work tomorrow so I didn't want to risk being hungover. Anyway, I had ONE bottle of Mike's Hard Lemonade, which I've never had before, and when I got home that night, I felt sleepy. I ended up dozing off a couple of times so I just went to bed super early (around 8) and woke up at around 10:45. My bf teased me that I nearly drank myself to sleep😂 Has this ever happened to you?
