Hangover

I feel like I have a hangover. I have no idea what that feels like because honestly I've never had one! But I'm sure it feels just like I'm feeling right now. Because of certain health conditions, I never drink anything with caffeine. Yesterday I was sooooo sleepy that I went ahead and drank a WHOLE can of Pepsi. It was disgusting! Anyway, I was still able to get to sleep. Usually, when I drink even a few sips of caffeine, I'm awake most of the night. Last night was an exception. I went to bed early - around 11:30 - and didn't wake up until 7 this morning. That's very unusual for me. But since I woke up, I've had a terrible headache. I'm pretty sure it's a caffeine hangover. If I drank coffee, I think I'd need a cup right now!
