i can’t get drunk?

in my defence i’ve never drank a lot of alcohol at once but ive drank like 5 shots of vodka back to back and im on antipsychotics and antidepressants that are known to make you feel drunk faster, and the most i’ve felt is like.. a little happier? but barely and its most likely environmental. Alcohol just makes my stomach hurt and makes me feel nauseous i don’t know.. i’ve tried so many kinds too, soju, vodka, fireball, wine, wiskey, gin. I don’t know maybe i just have a high tolerance? i’m not even a big drinker either, it’s weird.
