I have some links to information that should help answer your questions and make researching easier.
I suggest when you find a post that is of interest, print it out so you don't have to stay at the computer for an extended period of time. You could then take the pages outside and read while doing some "barefooting"...

Unfortunately there are no 'short' answers. Researching and educating yourself is the only way to "know" what your state of health is and "how" to nourish, cleanse, heal and rebuild is.
Please, ask all the questions you have.
If you are wanting help and guidance from Uny here is a list of questions Uny asks that you copy & paste into a new post and answer, so she has a more complete understanding of your personal situation.
