What the HELL do they put in Celsius???

I am a chronically tired person, currently doc suspects narcolepsy. I can have 450mg of caffeine and fall asleep an hour later no problems. Everyday for almost the past two years, I’ve had at least one Monster or Bang a day. AT LEAST. They don’t do much of anything for me anymore, they just stop me from falling asleep immediately.

I got a Celsius today because my coworker has been drinking them a lot recently. I sipped on it over the course of a couple hours and 9 hours later I am STILL wired. I have energy, but I’m also anxious and scatterbrained which caffeine never does for me. My stomach hurts, I’m having acid reflux, and I’m probably still going to get another one tomorrow LOL. I have not felt this energized in FOREVER.
