Can't Sleep

I'm battling insomnia1.
I cannot get to sleep
despite a rather valiant2
attempt at counting sheep.
I counted to a hundred.
Then I had a glass of milk.
I fluffed my little pillow
in its pillowcase of silk.
I made a pot of herbal tea
and drank at least a cup.
I sang myself a lullaby
and pulled my blankie up.
I plugged my ears with cotton balls.
I covered up my eyes.
I took relaxing breaths
and did a stretching exercise.
I've tried and tried to get to sleep
but just can't find a way.
It's looking like I'll have to
stay awake in class today.
