What’s wrong with me?

When I drink now, late at night after midnight I get this weird feeling my stomach, feels like I’m full of carbonated drinks and feel like im bloated or needing to burp but can’t. I get worried that trying to sleep it off I will throw up or something due to it coming up my esophagus. I don’t feel drunk or anything just have this weird feeling now. I used to feel fine drinking and would wake up and hardly notice if I drank the night before. Now, I get scared to over do it and often find my self not having a good time because I’m not trying to drink a lot like I used to.

Does anyone know any fix to this? I’ve tried Tums but it doesn’t really work that well. Is it something wrong that I need to go see doctor or does lack of sleep effect my body this way if it’s later at night and my body is used to sleeping at this time?
