at work today i chugged a extra strength 5 hour energy. call me stupid but caffeine can be a real help when i work nights. since my first, and so far only (i think), episode of anaphylactic shock three years ago, ive suffered from anxiety attacks related to my deadly nut allergy which seem to have gradually worsened in intensity. well today at work after the 5 hour energy, i was feeling a little jumpy at first but overall fine. then i started getting hot flashes more and more, which i realize now was probably just the niacin rush, until i went to my supervisor and asked him if i looked okay. he looked at me and said my face looked puffy and pale and my pupils were extremely dilated. i was immediately thrown into panic, I didn't have my epipens and my heart rate picked up and my mouth became extremely dry. i told him to call 911 which he did. now at this point i was 200% convinced i was having an allergic reaction, my tongue felt swollen and i was scared to death my airways were about to start closing. a cop came in a couple minutes later and started asking me questions followed by an ambulance. an emt sat me down and took my oxygen which read completely normal, although my pulse and blood pressure were obviously elevated. my supervisor called my parents as the responders reassured me that i looked completely normal and my vitals were nothing to be concerned about. i have always known the day would come where i tweak the fuck out so bad 911 would be called. im still not 100% myself and still on edge, though my parents keep reassuring me im not swollen or pale at all but i still feel a little itchy and my throat feels kinda tight. i dont know why my supervisor said i looked swollen, maybe it was the niacin rush? all i know is fuck 5 hour energy, never ever going near that shit again
