So apparently I have become a coffee lightweight! This morning I had just 16 oz. of America's favorite hot beverage...or as I like to call it "the sweet nectar of the gods"...and now I have a caffeine headache that will not go away! I used to be able to throw down mug after mug of coffee with absolutely no side effects. I wonder what has changed? When did I become a lightweight? And why won't this headache go away? Maybe it is time to switch to decaf? Anyone have any thoughts on my caffeine conundrum?
