Jet Laaaaaag

It's nearly 4 AM on Saturday morning, and I'm awake. Why? Because at 6 PM on Friday night, I was dozing in front of the tv, so lay down on the couch for a nap. And woke up 9 hours later. It's my 3rd night back at home, and it was an 8 hour time change from the UK. Grrr, you would think I'd be better at this.
