High on...coffee?

I just had my first ever double-shot latte. It was very nice...french toast flavored which is cinnamon with a bit of vanilla mixed in. I feel like I could run around the block a few...hundred...times. I had only about 3 hours of sleep last night and was previously feeling sluggish (like a wet sponge...ha!), but now I am now knee-bouncing, jittery, hands shaking, heart racing. So THIS is why people drink it! Forget Bayer aspirin, I think coffee is the wonder drug that works wonders. (I'm not the only person either...)
