How to cure the cogs ?

I ask the question to myself whilst lying on my bed
“Why on earth does my thoughts keep on thinking at stupid o’clock in my head ?”
Of course I do not get an answer from this problem that puzzles me
Oh if only insomnia diddled off and left my mind free

The time was twelve fifteen when it turned to two a.m. but each and every minute of that was without any seconds of REM
Dam, blast with blitherations I drive myself around the bend
If only I could cure the cogs in my mindfulness but that’s not something that I can mend

Alas I am my own worst enemy
I let my tinnitus take control
after tossing and turning so many times I get up and take a stroll
Sleeplessness is restlessness and doesn’t do us any good 
Yet my brain understands all this but it isn’t understood
Perhap’s I am a nocturnal creature
Maybe’s I should be a night Owl
Well that’s the only conclusion there is coz I am always on the prowl
