drunk or drugged?

so i went to a coworker xmas party at a bar. i drank only 5 beers and 3 (?) tequila shots. this may sound like a lot to some but its not out of the ordinary for me, and i stuck to beer (rather than cocktails) for the purpose of not getting that drunk. i’ve drank far more and have never been overly drunk. i also usually never throw up. in my 8+ years of drinking, i never have thrown up. tonight tho, i have blackouts of parts of the night and threw up multiple times at the bar. i also made sure to eat before i went, which is something i usually am bad with. i tend to go drinking with an empty stomach. im feeling weird about being that drunk, and i can’t tell if its embarrassment clouding my analysis or what, but i think its possible i was drugged. even my friends who took care of me tonight have seen me drink far more. they have also agreed it’s weird that i was that drunk. i don’t know if im being dramatic, and just trying to find an excuse for my drunkennness, or if this is something i should actually be worried about. please if someone can offer some advice or perspective? i just feel weird about it
