the Beatles said it best...

I'm so tired, I haven't slept a wink (okay, I have, just too few)
I'm so tired, my mind is on the blink (actually, the thermo and drama have wiped it out)
I wonder should I get up and fix myself a drink (coffee and oj--two, really!)
No,no,no.
I'm so tired I don't know what to do (well, truly I'm going to work!)
I'm so tired my mind is set on you (and you, and you, and you. you who? i'm just sayin' hi!)
I wonder should I call you but I know what you would do (answer the phone...or not)
You'd say I'm putting you on (it's an expression, not literal)
But it's no joke, it's doing me harm (the not sleeping)
You know I can't sleep, I can't stop my brain (it thinks in thermo CONSTANTLY)
You know it's three weeks, I'm going insane (this is true.)
You know I'd give you everything I've got for a little peace of mind (wouldn't we all?)
I'm so tired, I'm feeling so upset (actually I'm okay now, that was sooo two days ago.)
Although I'm so tired I'll have another cigarette (but only if I'm drinking----I prefer cigars)
And curse Sir Walter Raleigh (but only with the bad-haircut curse--it grows back!)
He was such a stupid git. (mmm-hmmm, stupid RTP!!!)

You know I'd give you everything I've got for a little peace of mind (wouldn't we all?)
I'd give you everything I've got for a little peace of mind (again, true, eh?)
I'd give you everything I've got for a little peace of mind (finis)
