Case of PnQ insomnia

I finish work as late as late
can be.
But the twitchy itch comes
haunting me.
Where's my pen and paper
the insomnic continues
its caper.

I scribble and scrawl
almost driving myself
up the wall.
Pillows are hot and bothering
my plot, to try and get some zzz''s
but then I battle with both my head's!
Up and down like a yoyo
start chanting...
Hi..Ho....Hi...Ho
I must to sleep I have to go!
No no no. Here it is
another night to go slow.
Then it's blooming morning
and now I start blinking
yawning!!!
