Do you have difficulty getting to 8 glasses of water a day? A dispenser like this may do the trick. Fill it with filtered/pure water and add mint leaves, fresh lemon or lime.  You can fill your thermos from it when you need to leave home.  If you prefer cold water you can set it in the refrigerator. (If you add ice cubes be sure they were made from the same water source).   This one comes from the West End Catalogue and is $55.00. More ideas await you at ReginaLeeds.com.
