Results of being on the Guaifenisen Protocol for Fibromyalgia ?

I am going to just be starting the protocol of the Guaif for Fibromyalgia, after reading Dr. Amand's book.
I know I have gotten other e-mails from people saying that they have been on it, but has anyone dealt with being very nauseated?
My doctor is ok with me trying it, but he says his other 2 patients have tried and could not tolerate the nausea.
Does anyone have any suggestions or advice they can give me about the nausea?
Has anyone else dealt with the nausea too?

Thank you for your time and consideration 😉
