I also have a hard time drinking water. But, ever since I bought a new fridge with a filtered cold water dispencer , I find myself drinking more water. I finally figured out that I do not like tap water, for no other reason other than tap water is not icy cold, like refrigerated water.
If you can pour yourself a quart of water into a container every morning and drink it for the rest of the day, it will be gone by the time you go to bed. Having it right there, pre-dispensed in a container, and cold, you are more likely to drink it as a matter of habit.
You may want to squeeze some citrus into the water (grapefruit, lemon, lime or orange). Some people add fresh mint, which is very good for you and also an appetite suppressant. I would not get into the habit of putting any sweetener, like sugar or artificial sweeteners, but a tablespoon of honey is very good in water....especially local honey if you have allergies, as local honey is the antidote to local pollen, which causes allergy reactions in those allergic.
You should drink 4 8oz cups a day, which equals a quart. Not 8 8oz cups.
