May have been drugged last night?

I should start with the obligatory “I cAn HanDlE My AlcOhoL I PrOmisE GuYs”, and you can choose to believe that at your own discretion, but generally I’m the last person in my friend group to get drunk every time we go out.

Last night my girlfriend and I decided to go for some drinks with one of her friends since she’s headed out of town today. It wasn’t any of our intentions to get legitimately drunk so I ordered GF and I a sex on the beach pitcher to split, which usually serves its purpose for her but only every really leaves me with a moderate buzz. We were all having a good time until I notice my ears were starting to ring, which I didn’t pay much attention to since the bar was doing a neon rave event and the music was loud as hell, but some 15 minutes pass and suddenly my vision starts going black, and in just a few minutes it’s progressed to the point where I can really only see the glow from all the bright lights in the bar. I leaned over to my girlfriend and told her I needed some air and went to collect myself outside, thinking it could have been a panic attack or something.

As SOON as I was out of the bar I could barely walk. My body felt heavy, I was struggling to breathe and I was sweating profusely. After dropping my phone a few times trying to text my girlfriend that I was definitely NOT alright i was able to get a semi-legible message through to her and she came sprinting outside with water. With the water I immediately felt SO much better, and I convinced her after a little bit that I was good hang out still but would be done drinking for the night.

Back inside we were waiting for the bar to clear up so GF could order another drink since she hadn’t gotten to finish hers earlier, and all was well until it fucking wasn’t, because the same thing started happening again after 10ish minutes back inside. First the ringing, then the vision, and then my motor functions accompanied by sweating and heavy breathing; only this time I was standing, as we had given up our booth during my first episode.

I hit the deck HARD, and spent a good 10 seconds slurring apologies to everybody that I was clumsily rolling into while trying to get up. I tried to explain what was happening to my girlfriend but struggled to find the words, and the ones that did came out completely unintelligible. She was eventually able to get me up and out of the bar, where I sat until I was good enough for her to walk me home.

I definitely drank the majority of the pitcher between the two of us, but my girlfriend is WAY smaller than me and a lightweight to boot. I know it’s probably not realistic to assume that someone spiked our drink and it somehow only affected me, but I have had severe alcohol poisoning before, and this did not feel like that, save for the clumsy movement.

With the knowledge that whatever I see here should be taken with a large grain of salt, does anybody have any clue what the hell happened to me? Is my ego just hurt and I’m looking for a reason to believe that I wasn’t THAT guy at the bar?
