When I went under the knife two years ago, my doctor learned how dehydrated I was prior to that. My internal organs manifested it. My liver was so dehydrated. She strongly advised me to keep myself hydrated. With my weight, I am supposed to have three liters of water. I never had a way to find out if I really did have even at least a liter a day. Well, this is a very interesting way to make sure you drink up enough water a day. I stumbled upon this in Pinterest.com. (Yeah, I am another Pinterest addict.)
So each container can hold up to a liter. Having three of this, I can split up my required 3 liters daily water intake. What do you think?
