Also, on the days where you're drinking beer - have you eaten and drank water like you have on the days where you drink wine? Like are you drinking the wine with a big meal? Eating and drinking a lot is the best prevention for a hangover. I get weird ones all the time even like between different types of beer and I've narrowed it down to most likely be poor eating / drinking habits the day I drink. Having food in your belly is just as important as staying hydrated IMO.
