18 Hours of Travel and a 9 Hour Time Difference Will Do That to You

My clock is so off. It's day three back home and I can't sleep like a normal person. I'm wondering if Hannah's home yet. Courtney just got home. I can't wait to call Anna Maria and tell her we're both a-OK. I find myself waking up at the oddest hours (ahem, 2:52 AM at present) and unable to fall back asleep, or falling asleep at my earliest convenience (8 PM) and waking up before the birds (7:15 AM). I haven't slept like this since grade school. Is part of jetlag having the sleeping pattern of a 5 year old?
