WTF happened to me?

So I don’t drink a lot, and never had a drinking problem. I did have my fair share of fun when I was in my 20s, but these days (40) I will have 1-2 beers with dinner in the evening, probably 3-5 days a week. Some weeks this falls to maybe 1-2 days a week, as it has for the last few weeks. I rarely have more than this now. Almost never actually. The last time I had 3 beers was probably my 40th birthday in May. If I have 4 beers I am hung over for like 2 days it’s not worth it. Since turning 30 I just can’t handle it like I used to, now that I’m 40 there’s just no way.

So anyway, my point is I drink in moderation. The other day it was completely ordinary, and I had one can of beer. It was only a 4% so I decided to have another while we watched a movie or something. Mount Crushmore pilsner for anyone who cares. I felt completely fine when I went to bed, just like any other normal day. Could have easily driven obviously it was like 2 standard drinks over 2-3 hours.

The next day though, I woke up and the fucking room was spinning and I felt like I had had 10 beers the day before. I seriously haven’t been this hungover in probably 10-15 YEARS. The spinning and general feeling of malaise lasted the entire day, with the room spinning until 3pm. I managed to have electrolyte drinks, tea, and a lot of water and salt, and then the next day (today), felt pretty much normal again.

For a weekly timeline I had 2 drinks (5% beer) with a friend last Saturday, and felt COMPLETELY fine the next morning (could have run a damn marathon) and then my next time drinking was Thursday, then this happened Friday morning. But from Sunday to Wednesday I went to the Gym, worked out, and hit the sauna 4 days in a row which is about double my usual gym attendance.

Was I just dehydrated as hell? Was the beer off (it tasted fine)? Is my tolerance just off from drinking less than usual? There’s no way I was drugged… I was at home on my couch. Anyone had something like this happen before?
