the search continues

I can't find my mind today.
Have you seen it?
Will you help me look?
I remember I used it
late last night when trying to
figure out how much
sleep I was going to get
if I actually went to bed.
But I'm not sure if I did.
All of the sudden,
it was morning
and I'm at work,
and I don't have
a clue what is going on.
Can you help me?
