Help - water intake and absorption

[Gary Thomson]

I am presently reviewing methods of improving the intake and absorption 
of water into the body. Of concern is that even if fluid is readily 
available to  soldiers they will go into voluntary dehydration rather 
than drink from canteens. We are looking at ways of making ingestion 
easier. One commercially available device is a bladder with a tube, this 
means is often used by bike riders. Has anyone had any experience with 
this sort of device? Any other ideas on making the act of ingestion 
easier? Replies by E-mail would be appreciated
