I'm So Tired

I'm so tired, I haven't slept a wink,
I'm so tired, my mind is 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 it's 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 such a stupid git.
