Wallflower

I have the SAME problem. Very simply, drinking water makes me feel very sick! I can't drink pure water, water from the tap, or water from a water bottle. I can't drink water other than flavored water. That isn't a problem really, I can live on flavored water for the rest of my life, I don't really mind. But my problem starts when I run out of flavored water and I can't go shopping for more for a couple of days. I become very irritated because I would be VERY thirsty, and I would be tempted to drink water, but I know that if I do, I'll just become ill. HELP?!
