Does anyone else experience this?

I am not an occasional drinker. Even on holidays or birthday celebrations, my family will oftentimes say “Oh come on, just have a couple” and then I do. Don’t get me wrong, I enjoy a fun buzz, but I don’t use alcohol to necessarily feel. Anyways, every single time I drink , I can drink a few drinks and I feel fine, but hourssssss later I start to feel sick or nauseous, so I’m just wondering, if anyone else experiences upset tummies hours after drinking? The crazy thing is, I feel fine when under the influence. It’s always when the buzz is gone, that I feel off. Thanks in advance!
