Dear Insomnia

Thanks insomnia for a fantastic night,
No sleep, gee, what a delight,
I try to sleep without a light,
But the dark is such a fright!
With monsters height as big as BIG BEN,
I shall duck in my den,
For one day, you insomnia will be in a pen,
And I might call you Len.

Insomnia, something I can't budge. I had 5 hours sleep, new record I am sure! Maybe tonight I will have a much better night sleep or maybe not!
