Exploring options is such a good idea. Power is knowledge!
I'm on the guafenesin protocol. There are no bad things to report. The drug is well tolerated and does not cause allergic reactions. BUT, you will go through some cycling which can be down right annoying at the start. Eventually you do become better. You have to find the exact dose that you can tolerate and stick with it. If you dose yourself based on some self-formulation, you can find yourself in bad shape or possibly not have enough of the medicine in your system to remove the fibro gunk. So I suggest you read the book "What Your Doctor Won't Tell You About Fibromyalgia" by St. Amand (the pioneer doctor who developed the protocol). Make your own decisions. Do not let fear get in the way.
And, by the way, the reason I didn't start with the Teitlebaum protocol was the expense. Guafenesin is, by far, the cheaper of the two options. I'm so glad I'm cheap.
I was almost bedridden. I now ride ATVs, horses, bike ride, go fishing, enjoy life. This too can be you.
