Why can't I sleep

Why, oh why can't I get to sleep?
I've tried everything like counting backwards
And even counting sheep


Lavender oil on pillow
Or a hot and milky drink
Why is it when I go to bed
I always lay and think?


Have I locked all the doors
And switched off all the lights?
Tired all the next day
Due to sleepless nights


I really need to switch off
From the worries of the day
But things that have happened
On my mind they play


I need to cut down on my caffeine
Cos my B.P. is hitting the roof
It's one of the reasons I lay awake
I don't need anymore proof


It's a small price to pay for a decent night’s sleep
So now I will finish this rhyme
Off to Dreamland I’ll go with a calm rested mind?
Till the alarm on my clock starts to chime
