Crazy congestion when drinking alcohol?

I drank for the first time over 2 weeks ago, and while I was outside I could feel lots of itching in my throat and it was runny. When I got home and wanted to sleep, I was so congested I couldn’t breathe through my nose + runny, my eyes were watering and itchy, etc. I didn’t sleep that night, and I was sick for almost 3 days like that. That night I had two sex on the beaches, a jaegerbomb and two snake bites. (This was super spaced out and I had a 3 course meal in between so I wasn’t drunk at all.)

A few days ago I went out again and had 3 beers and a snakebite. At some point I was feeling sick so I went home and tried to go to sleep immediately to try be faster than the congestion (idk😭 I thought i could try!). Obviously it didnt work. Come the worst congestion of my life + runny nose + sinus pressure + itchy throat + no sleep death combo. But this time it only really lasted a day and I could sleep the next night.

Ive looked online and maybe I have an alcohol intolerance? Also I’ve seen similar symptoms explained on here but none were to my extent of losing sleep. Its always gone in the morning or they wake up to it.

So im wondering has anybody experienced this or know what it could be? Any help would be really appreciated.

So annoying though because I wish i could have fun like everybody else!!! I’ll probably give up drinking altogether.
