Sleep

I have been having trouble sleeping while I travel. I usually go to sleep around 9:30 - 10:00 pm and periodically wake up through out the night. Normally I get enough sleep even though this happens but last night I woke up at 4am and could not get back to sleep. It's now 6:30 and I've made some coffee, talked to Brenda and watched some tv. I am pretty sure I know why I have had trouble sleeping I just need to figure out how to fix it. Today is going to be a long day.
