Caffeine

I think I'm addicted to caffeine.  I had a redbull this morning and I'm pounding diet coke right now.  I feel tired and sluggish if I don't drink anything with caffeine in it during the week.  I'm not at the point of getting headaches if I go without it, but I can't get through a work day without a bit of it.  It really should be a drug based on its addictive qualities.  Caffeine...a drug?!  Bob Saget would disagree.
