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 would 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.


Lennon wrote the song at a Transcendental Meditation camp when he could not sleep
