I drink beer all the time. Well not ALL the time, but you get my meaning. Part of it depends on what you like and part of it depends on how well you handle carbonation etc.
I can drink heavy stouts like guinness, but only in moderation. Drinking guinness, to me, is like drinking an ever-expanding protein shake. I couldn't drink it all night, no way could I keep that down. That may be a factor for you, it could be the "liquid bread" factor - depending on brand, it can be heavy or very filling.
It may also be that the grains used in some beers are not compatible with you. Just as an example, fennel makes my dad very nauseous and it doesn't sit well with me either.
Belching is good when drinking beer. Keep it quiet if you like or belt it out, but carbonation is going to fizz out once it goes down and you're going to have to get rid of it. You might have things in your stomach that carbonic acid will react with, the lining of your stomach has
lots of surface area that creates sites for reaction, and the sloshing and movement helps the CO2 gas out as well. It's almost like a vinegar and baking soda party in there. I can swallow air at will (and unfortunately it goes the other way, including acid reflux) so burping quietly has never been a problem. Not that it matters, we burp all night and no one gives a damn. If I was with company that gave a damn, I wouldn't be there to begin with
I used to chug liquor in middle school (yeah started early lol) and chase it with beer. I can't do that now, acid reflux makes my esophagus a little tender so if I do shots with friends, I only do a couple, and I chase it quickly. And wine? Ugh. My wife is italian and she LOVES wine. I can't touch it, it makes me ill. I can drink tequila all night, but wine will make my stomach catch fire and burn me down. I'd have to pop about 3 pepcid ACs after a glass of the stuff.
In Texas we chug like mofos. We chug in high school and we chug in college. We do beer bongs, keg stands, timed beer matches, at A&M we did ring dunking where you chug the pitcher...you name it we do it. Some of your intolerance may just be in your upbringing. I grew up drinking beer on party night like water, so of course I can drink a whole bottle in one continuous gulp, and then do a few more right after that. If you can't, maybe you need a little more practice
Find some rednecks, hit a pool hall, and drink like they do. Burp loud enough to make people turn heads. Let loose and crack up. You'll probably puke a few times, but you'll quickly catch on.
