Wake me, shake me

I'm sleepy and out of it! I didn't sleep well last night. I ate late at night, I think that's what did it.
I went to the gym early this morning too. It usually gives me more energy but not today. I am going to eat lunch and drink a nice cold drink, that should pep me up! Plus go for a walk over to do some window shopping. Some nice sunshine should do the trick. What keeps you awake?
