Sleepy

On vacation, I am never up in the 5 o'clock hour. I go, go, go and hope to have a few minutes to relax. I run around after N like a crazy person and even manage some adult conversation. And yet today I feel beat. So sleepy. What do you think it is? The early am or being alert all day and sitting in a yawn-yawn mtg. Who knows but I am so happy that D was on cleaning this evening, dinner was ready when we walked in the door and N went down early and w/out a fight. So sleep you rang and I am more than happy to answer :P
