What do you do to handle fatigue during a long tournament?

My 2 big tourneys wins were 11 hours ($3 rebuy on Stars) and 9 hours i think for paradise.

I wasnt tired and they both finished at 10am my time nearly

I think 9 hrs would kill me! 10 minutes after the third break I am going "Good God isn't it break time yet!" I would love to hear how some of you long haulers handle it. I played about 8 hours last night, but they were all small tourneys so I had time between. And I was still dead when I quit.
