<<Disclaimer: Verify this information before applying it to your situation.>> I was diagnosed with fibromyaglia about 10 years ago. I had the basic all over muscle stiffness, lumps, pain & spasms; foot & hip pain; hobbling walk; fatigue & brain fog, depression, etc. I started the guaifenesin protocol in January of 2000. After 10 months I no longer had muscle & foot pain, my brain fog was somewhat improved, but I continued to be very fatigued. About that same time (October 2000) I began to have a distressing new symptom, chronic severe upper GI upset. I thought it was the guaifenesin that was upsetting my stomach, so I stopped taking it. Within three weeks all my FMS symptoms returned, I hurt all over just as I had before I began the guaifenesin. I couldn't take the pain anymore so I went back on guaifenesin & within a few days all the pain & stiffness were gone... again. I started looking for solutions to my constant gut pain which continued to get worse & worse. To make a long story short, in April of this year, I got diagnosed with gluten enteropathy/intolerance [celiac disease] and went on the gluten free (GF) diet. I began to experience blessed relief from the GI problems and feel tons more energetic. The depression & brain fog lifted as well. I felt well for the first time in years. Just a month ago, I decided to go off the guaifenesin again to see if the FMS symptoms would return as they had before. The symptoms did return and again melted away once I resumed the medication. Now, because I feel well most of the time, I often forget to take my guaifenesin. Everytime I skip a few doses, I start to feel twinges of pain here & there. When I get back on schedule, I get relief. I now walk with a smooth even gait & my muscles are smooth & flexible instead of lumpy & stiff. But, best of all, I HAVE NO MORE MUSCLE PAIN! It's now clear to me that I have two separate disease processes going on & that each needs its own treatment. The guaifenesin protocol (according to Dr. St. Amand) is the treatment I need for fibromyalgia and the gluten free diet is what I need for my gluten enteropathy [celiac disease]. Based on my personal experience and what I've learned on this list serve & in my reading, I believe that FMS & CD may be somehow related, but I believe they are two separate & distinct diseases. In support of my opinion is the fact that many celiacs having been GF for years suddenly develop symptoms of FMS. And many of those with FMS do not get well on the GF diet. In my humble opinion, if you were told you had FMS & got completely well on the GF diet, you never really did have FMS in the first place, you had only CD. For those with CD who have been told they have FMS, I suggest they try the guaifenesin protocol for a year to see if their condition improves. Conversely, all those with FMS should get tested for CD since the symptoms are so similar. A brief synopsis of the guaifenesin protocol for FMS can be found on the internet at the following websites: http://www.netromall.com/guai-support/ http://www.guaidoc.com/ The protocol is discussed in more detail in the book "What Your Doctor May Not Tell You About Fibromyalgia" written by Dr. Paul St. Amand & Claudia Merek. The authors both have FMS and are so sincere in their deisre to help others that they are donating proceeds from the sale of this book to FMS research. ~Valerie in Tacoma, WA, USA
