The first time I had a big dose of caffeine was in one of those 5 hour energy shots yeeears ago when I worked the graveyard shift. I took one at lunchtime (3am) and was flying for the rest of my shift! Starting taking it more often and got raises and awards like crazy. That was about 4-5 years ago and I'm still addicted. Now I take caffeine in pill form just to feel "normal". Which is min 800mg a day. I'll stop.. eventually. lol
Caffeine pills are misleading. They make you feel so excited, but deep down you are so scared.
