I'm so tired

I'm son tired, I haven't slept a wink,
I'm so tired, my mind on the blink.

I wonder should I get up and fix myself a drink.
No, no, no.
I'm so tired I don't know what to do.
I'm so tired my mind is set on you.
I wonder should I call you but I know what
You'd do.

You'd say I'm putting you on.
But is't no joke, it's doing me harm.
You know I can't sleep, I can't stop my brain
You know it's three weeks, I'm going insane.
You know I'd give you everything I've got for a
Little peace of mind.

I'm so tired, I'm feeling so upset.
Although I'm so tired I'll have another cigarette
And curse Sir Walter Raleigh
He was a stupid git.
