Guaifenesin protocol. Anyone tried it?

I just saw an article about this as a treatment for fibro. I guess it is one of the active ingredients in mucinex. It doesnt have much more than anecdotal evidence but I am wondering if its worth a try. I am nor completely sure but I think you take it twice a day and then you have to stay away from salicylates..which are in a bunch of things. Wonder if anyone has tried it?
