Dr. St. Amand and The Guaifenesin Protocol

Has anyone tried Dr. St. Amand's Guaifenesin Protocol for fibromyalgia? Featured here:

One of the biggest deterrents for people is the avoidance of Salicylates, which is in quite a lot of foods, supplements, beauty products etc.! Salicylates are also found in  many organic, all-natural products - all plants produce it as a protective agent against soil bacteria. Without salicylates plants would never get out of the ground alive. Thus "all-natural" products actually contain more salicylates since they have not been processed out.

I've been flipping throu Dr. St. Amand's book, "What Your Doctor May Not Tell You About Fibromyalgia" detailing things like this.

Curious if anyone has tried and their thoughts on it.
