Odd hunger pains(not hungry) two days after getting wasted

TLDR- drank too much two days ago and now my stomach feels odd, am I overthinking it?

Im a 22 yr old female about 125lbs(5’4) I rarely drink ill have a small drink here in there. I indulge once every few months. So I honestly haven’t got drunk in a very long time. The other day i drank more than i can handle and underestimated what i was drinking. I drank about 80% of a pint of 1800? The red one . I mixed about three cups and i was veryyyy drunk i threw up and after i knocked out. After i threw up i don’t remember absolutely anythingggg i know i fell asleep but then i woke up arounf 3ish to walk my friend out and i came back locked the door and went back to bed but i dont even remember that. When i get wasted like that its scary because i cant recall anything …anyways i woke up the next day very out of it almost drunk like when i woke up and spent the whole day trying to recover. Honestly it was a weird feeling because when i get wasted im used to getting a hang over where i have to puke it out and i feel immediately better after but honestly it just lingered and today i feelt very fatigued and now im feeling this gnawing pain in my stomach like im starving but i know im not… i looked it up and it could be a stomach ulcer but am i over thinking it?
