I agree, but if you check out lots of these med threads, there seems to be the perception (perhaps just by me?) that everyone thinks a little aspirin is the same as a cath lab. It's not. (disclaimer: I'm kind of in a pissy mood these last few days, so there's a good chance I'm just projecting it)

Enough of my soap box, I'll actually contribute something useful.

Someone mentioned rice water and charcoal for diarrhea. I can't comment on the charcoal, but we use something called Cera-lyte in our aid station for diarrhea. It's rice based, tastes horrible, but helps "plug up" and rehydrate.

Additionally, the US Army has put out a memo that a 20oz Gatorade G2 w/ 1/2 gram of salt mixed in is a good field-expedient version of the latest WHO oral rehydration solution. I'm not 100% positive, but I think the typical "fast food" salt packets are either 0.5 or 1 gram of salt. Might be worth snatching a handful if you're doing some long-term outdoor activities. It would be REALLY nice if G2 came as a powdered solution.
