In high school (when I was stupid) I used to regularly drink Monsters, Rockstars and other various energy drinks. I absolutely loved there taste! Then I started to get migraines. With time I found out that if I consumed an energy drink (anything with more than 100mg. of caffeine) I would give myself a massive migraine headache that required me to go to the hospital. Though I don't think a few incidences of caffeine overdose will shut down a super company with an almost an occult like fallowing like Monster Energy.
