Hello Claudio,
I know this might be a bit late since most of the posts on this thread are from Jan/Feb.

However, I wanted to share that I have CFS and have had for the last 11 years. I am also a patient at the Atkins Center in NY, and it was Dr. Atkins himself who diagnosed me.

Virtually all other doctors I've dealt with (due to moving had other doctors too) have tried to tell me it is depression, anxiety, etc. Well, it isn't.

Each person required different nutrients/supplements for their individual condition, but I recommend that you get the book;
THE VITA-NUTRIENT SOLUTION, BY DR. ATKINS. In there you will see what is recommended for each illness and how much.

If you cannot get stuff locally in Buenos Aires you can order online.

Good Luck
