Water
Apropos of yesterday's water discussion, here's some absolutely useless advice about how to tell if you're drinking too much or too little water:
Initial symptoms of over-hydration include dizziness, nausea, apathy and confusion. However these symptoms are also associated with dehydration - so it's important to be aware of how much you are drinking.
At any rate, I'll say that it never occurred to me that over-consumption of water might be a problem, but apparently it can. Maybe I'll have to make this New Year's Resolution 2008. This, though, seems like the sort of resolution that will prompt people to look at me funny.
