What happened to me?

Long story short, I’m (29F) no longer to enjoy any type of alcoholic beverage without feeling stomach pain/getting ill. This started happening around 23 years old. I used to be able to get drunk and barely have a hangover.

A couple mixed drinks like margaritas usually ends up with a stomachache for the rest of the night that I need to stay awake to fight off. A tipsy feeling ends up with me feeling this way.

If I actually get DRUNK (the last time was probably a year ago) I get violently ill, and have stomach pains and vomit that’s equivalent to the stomach bug. I’ll throw up for 12-15 hours until I’m dry heaving for hours and hours, but the pain is still there and terrible.

I recently was diagnosed with the autoimmune disease Hashimotos (hypothyroidism) and I’m wondering if it may have had anything to do with it.
