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
