Iron, this is really helpful and very well documented. I read a lot in the past about kidneys and bladder, and that is really remindind me of what I had retained. I don't drink very much as I am always in the washroom when I drink. I think it is a vicious circle. I really value your information and I wish I will have the courage at one point to take care of it. AFter I am moved in my house this summer, I will unless it becomes urgent before. Thanks Iron!
