As a fellow insomniac myself, I can sympathise. I can count the times I've had a full, uninterrupted 8 hour night sleep on one hand ... and I'm 40. I mean that literally too ... I've had maybe four nights of full sleep in my entire life.
Like the man himself, "I average about four or five hours a night I guess ..."
And in case you're wondering (), the longest I was ever awake and simply could not sleep was 78 hours. No, that's not a typo ... 78 hours straight in late 2004.
Good times ... !
