I did this at the pool once. First time doing basically any real workout in a year or two and only managed about 10min of laps before i had the same weird bad feeling. Luckily i managed to get out and sit in the grassy area before i was sick, so i only ruined the day of whoever cleaned it up, and didnt close the entire pool

Yup i just saw a post about a guy who started drinking energy drinks as a kid, trying to get the same hyperactivity as his friends. And now he's an adult with nerve problems from the vitamins and whatnot building up

Btw some people (more common with adhd and autism) dont get energy from caffeine but can still develop health problems from drinking too many energy drinks
