Thanks for that info, I love the comment about the doctor! I live in the UK, and my water has no fluoride either. However it is quite hard, which means soap doesn't lather well. That's one of the reasons why I have decided to go straight into "no poo". I'm hoping that cold turkey is the quickest way to make my body go back to it's normal production of oils. I think it helps that I previously did a fair bit of detoxing through water fasting, and I am currently on a healthy plant based diet, that may speed up the process - well I hope! I use the gym every day, and like you I shower in water only.
