http://www.sportline.com/products/hydration-2/hydracoach.htmlI tracked this down after seeing it on pinterest. It's called the Hydracoach Intelligent Water Bottle. It's got a digital monitor to track how much you are drinking. It's only about $30. I think it could be good for both D patients and transplant patients, but not sure if it's programmable for the smaller amounts for those on limitations. Gotta say I'm tempted for busy days now that I've had my transplant. It's really easy to get busy and lose track of how much I've had to drink.
Has anyone tried one? Pre or Post transplant? Is it worth the cash?
