Hey Rob,
I contracted G. Lambia during an Ex in the Pisgah National Forest many years ago and I just damned near died. At one point, I lost 18 pounds in 24 hours. The stuff coming out of my mouth and my "other end" was identical in appearance and smell.
<b>Identical.</b> (Skip this situation if you ever get the chance.)
I couldn't keep down a glass of water, or any other fluids. Solids were out of the question and anti-diareal (sp?) suppositories were a waste of time. Couldn't keep them in long enough to even begin to work. The cramps were constant for almost two weeks and of a painful intensity I'd never have believed possible until I experienced it.
I was in and out of consiousness, started out on "Quarters" and "Bedrest" at home, and after three days, when my wife couldn't wake me, got the neighbor to carry me (no mean feat!) out to the car and take me to Womack Army Hospital. I stayed there on constant IV drip to keep from dehydrating and to be honest, I really have little recollection of what else was done to keep me from kicking off, but I'm told it was a near thing a couple of times.
I was over a month getting my strength back and lost a significant amount of muscle mass during my illness. (A really weak word for what happened.)
Sorry if this is "too much information", but I want to make sure everyone understands how serious that something as "minor" as G. Lambia can be.
Without hospitilization, I would have died horribly. In a survival situation, with no medical facilities at hand, G. Lambia is an almost certain death.
You bet, I'll take the water filter!
