You could be hypersensitive. Caffeine is a drug, after all. It's one of those common ones that people are addicted to and don't even notice or care. I eliminated it from my diet when I was in high school and had stunning results. Now the only time I use it is when I'm distance driving because I tend to get really bad road fatigue. Three sips of Dr. Pepper and I'm ready to go. Any more than that and I start shaking.
