You really need a practitioner. All I can do is refer you to Dr. Wilson's site with ?'s about distilled H2O. My dr. said to use either RO water or spring. All I drink is spring, per his instructions, but he approved used RO for the enemas and cooking. On the trace minerals, I have no idea. Again, check out Dr. W.'s site.
If enemas are what keep you "going", I don't know what Plan B will be when you are moving. Does your GI dr. have a recommendation? I do hope you have an excellent GI since you have some very serious issues.
