Caffeine

I have definitely reached the point where caffeine has become almost like an enemy to me. There are times, like today, when I feel tired enough to justify a can of Dr. Pepper at lunch. But I fear not being able to sleep tonight. I seem to have quite a reaction to even the tiniest bit of caffeine since I gave up regular consumption of coffee/caffeinated drinks. Even when I order decaf drinks, the small amount of caffeine still affects me. The good thing about all of this is that when I need a boost, caffeine works- whereas in the past, I could go and take a nap after a cup of coffee. The downfall is that it now sometimes works too well... I should really just eliminate consumption, instead of limiting consumption.
