wine causing long lasting sickness???

i’m not a heavy drinker, but i do drink once every other week. i know my limit is around 6 units as i’m quite small. my usual drinks will be cider + vodka mixes and i’m fine with no hangover at all, however the other day i stayed within my limits but had an aperol spritz and for some reason it had me spewing for an hour and then i blacked out in a taco bell for 45 mins whilst shivering. the nausea didn’t leave for 2 days and the stomach pain is still here three days later. literally why? i’m assuming i have some sort of tolerance issue with wine and prosecco as back in march i drank half a bottle of wine and was throwing up for weeks with insane fatigue and pain. i can’t seem to make it make sense but i wanna know if anyone else has experienced this or something like it and knows why this is
