I only smoke weed when I need to

I only smoke weed when I need to,
And I need to get some rest,
I confess, I burnt a hole in the mattress,
Yes, yes, it was me, I plead guilty,
And on the count of three I pull back the duvet,
Make my way to the refrigerator,
One dry potato inside, no lie
Not even bread, jam,
When the light above my head went bam!
I can't sleep, something's all over me,
Greasy, insomnia please release me,
And let me dream about making mad love on the heath,
Tearing off tights with my teeth.
But there's no relief,
I'm wide awake in my kitchen,
It's dark and I'm lonely,
Oh, if I could only get some sleep,
Creaky noises make my skin creep,
I need to get some sleep,
I can't get no sleep....
