This is very interesting. I feel better drinking more water, though. Water is my "coffee" since I don't drink cafieine anymore, and it surely helps wake me up in the morning. There is rarely a night I don't wake up with a very dry mouth/throat here and need a few sips of water. It could be the different climate that I'm not used to. I never drink soda, mainly water and tea. This is something I might have to look further into on my time off. Fasts certainly do have their benefits, but they are not good for an extended period of time.
