I typically drink six 750 ml (yes, I'm in Canada and use the metric system) containers of water while at work. I used to use Crystal Light for maybe two of those each day. These days though, if I want a little flavor added to my water, I throw in a scoop of Orange flavored Metamucil. May sound weird but I figure the fibre is beneficial and makes the water more palatable. And it's not that I need the extra fibre as I eat plenty of veggies, oatmeal and brown rice but think that the little extra fibre doesn't hurt either. Just my two cents.
