Hmmm sounds like there could be something there. I have always been under the impression (by impression I mean I was taught this by my various exercise science professors) that caffeine pulled water from the interstitium. Which thereby was turned into urea and then excreted from the body as urine. Now the problem here is that if he isn't seeing any change in urine amount then that is definitely worth looking into. I think that the effect of caffeine pulling water from the interstitium unnecessarily is what causes the dehydration.
But then again i'm not the one doing my grad work on it. My grad work involves the correlations between positive thinking and mental resilience, now that is some crazy stuff!
