If you or your patients are having difficluty managing your fluids, you might try a DigiStraw. it is a "digital straw" to track how much you drink. I am a kidney transplant recipient and after 10 years now back on hemodialysis.

I invented and patented the device some time ago to help me with my fluids-it helped me quite a bit. I am making the device available to the public in several months.

Go to www.digistraw.com and see if it might work for you.
