Hey, I wasn't giving advise, and coffee and cookies are excellent sources of cookie and coffee, 2 very important food groups. Besides, you're just mad you didn't think of it.

I did some more research (sorry Sandy, I can't count sponsored studies, I just don't believe that there isn't any bias.) and found an independent study on sweat rates in professional football. The rates during practice ranged from 1.4L/hr to almost 4L/hr. WOW! At this point I think I'm a believer in replacing sodium at a rate of 790mg/L of water consumed (staying within the recommended daily sodium intake in relation to the recommended daily water intake and taking into account the accelerated sweat usage caused by running.) This almost perfectly matches your salt tabs.
I am still concerned about the long term effects of this increased sodium intake on my cardiovascular system, as I can't find any reference to mitigating factors in increasing useage of sodium (output). I do realize that lack of electrolytes can quite quickly kill me in the short term, I'd like a little reassurance that all this salt won't kill me anyway...
