Wound up in the ER after 3 days of a $12 gas station "energy" drink I thought was harmless
I drink one coffee in the morning and that's it, so I figured adding a cheap energy drink for a work crunch was no big deal. By day 3 I was shaking at my desk, my heart was pounding at like 110 while sitting still, and I couldn't sleep more than 2 hours. Turns out the label said 300mg of caffeine plus whatever mystery blend they don't list, and I had been drinking them at 4pm on an empty stomach. The ER doc in Sacramento ran an EKG, told me my potassium was low, and asked what I'd changed. I'm fine now, but it scared me how fast it stacked up. Has anyone else had a bad run with pre-workout or energy drinks like this?
