For Fibromyalgia "When I first started the protocol, the pain got much worse - this was the phosphate deposits leaving my body, which hurt as much leaving as they did coming in. As I stayed on the protocol, this got much better. I have been on the protocol for 25 years. Still taking guaifenesin and have no more complaints of Fibromyalgia."

Mucinex (guaifenesin) for Fibromyalgia "Mucinex made my pain disappear if I took it along with a painkiller but not only that, it made everything better. All of my fibromyalgia symptoms were gone, but that may have been because I was taking Ginseng for energy and ginkgo for fibrofog. I still love Mucinex, it saved my life."

For Fibromyalgia "This is a hard one. I have read nearly everything there is to read on Guaifenesin and Dr Anands treatment. I recommend you do the same. Have I improved? Yes, very much, I think... I need to go back and get mapped again. The confusion is the length of time of treatment, and if you are blocking or not. You must journal and map, or over a 6 months you just are not sure of improvement. Some pains are the same but the brain fog is completely gone and I have much more energy. So life still sucks but not as bad as it was six months ago. It it the Guai? I think so??? I hope so? Btw, those of you that gave a 1 star because you felt so tired? Well that is exactly how you were supposed to feel. Oops."

Mucinex (guaifenesin) for Fibromyalgia "I have been using Mucinex for 6-9 months for Fibromyalgia and Chronic Cough (20 years). Started with 600mg twice a day for about a month, then I switched to 1200mg twice a day for about 2 months. 1200 was way TOO Much, it made my joints burn with pain and my left leg swelled up. I switched back to 600mg twice a day - still had the pain and swelling - then dropped the dose to 600mg once a day - the swelling went down and the pain was much less. I got very tired -hard to work. All this time the Mucinex worked to control the Fibro and helped me to function and think clearly. I will try an even lower dose of Mucinex. Can't get it over the counter. I've been off the medicine for 2 days with lots of rest. In a few days I'll be back on with a lower dose."

For Fibromyalgia "Suffered with pain and fatigue entire adult life, but in 2008 I was bedridden from fibromyalgia & fatigue. This is not a quick fix, nor is it a cure. It is a treatment I will use for the rest of my life. The protocol is complicated and can be expensive, depending on your required dose. I had eat a low-carb diet to control my fatigue. Each year since 2008 has been measurably better. This protocol is most difficult for the "natural" crowd - no herbal supplements, must avoid most "natural" skin products - but for me it has been well worth it. I am stronger and in less pain than when I started this. Most important, I am not bedridden."

Mucinex (guaifenesin) for Cough "I was suffering from a severe virus-caused sore throat with terrible coughing. My PCP advised me to take Mucinex but at substantially greater dosage than the package recommends. I did so for about 3-4 weeks. The medication did help relieve my coughing, but it interfered so badly with my sleep that I had to discontinue taking it. I notice that other people have experienced sleep problems with Mucinex. There should be a warning about this on the package label."

Mucinex (guaifenesin) for Bronchitis "I read many reviews some positive and some negative. But people need to remember it will work for some and others it won't. In the 80's my allergist prescribed "Guaifenesin" for me. It really was the best for me. Then it was taken off the market for a while. Several months I was looking for something to help me with my congestion and allergies. Found Mucinex and have been using it as needed and I feel great."

Took regular Mucinex generic label. Felt like I was drowning. Post nasal drip putting fluid in my lungs and I was drowning. Please go to the Dr. if this sounds like you - it turned out I had Community Acquired Pneumonia."

For Fibromyalgia "I used the guaifenesin protocol for about a year, and completely reversed all fibro symptoms. My fibro symptoms occurred very rapidly, and I noticed that the change seemed to occur about the time I began applying those wonderfully scented lotions/potions to my skin nightly from places like Bath and Beauty, etc. I started researching and began the protocol after reading the book. I was completely better within a year, I would guess. I have stopped using Guaifenesin for 3-4 years now and have no recurring problems. I think I swamped my system so fast with salicilate products, and all those ingredients on the "do not use" list, that it was easy for me to quickly remove them from the lumps I had mapped by a specialist."

Mucinex (guaifenesin) for Bronchiectasis "Works great for thinning mucus in the lungs. People with bronchiectasis may need to double up the dosage. People with a flair-up may not notice a big change at first as it’s gentle acting. Check with your doctor of course but this is a fairly safe medicine. I use it daily to keep passages clear."

For Fibromyalgia "I have been using Guaifenesen for 10 years now. Like my Doctor said, I had initial relief, then cycled between feeling worse and better, and now my CFS / Fibro is much milder than it was. I avoid Salicylates, but accidental exposure isn't a disaster, since I am not a strong blocker. For me, it works best just before or just after mild exercise, like a 1 mile walk to work, or mowing the lawn. I take 1/4 of a COSTCO 400 mg. Tablet whenever I feel Fibro pain, or before anticipated exercise, or after unexpected exercise."

Mucinex (guaifenesin) for Fibromyalgia "I had a terrible experience with Mucinex. I followed the protocol for just over 1 month hoping to feel some relief but I felt really heavy, like I had a bad flu, and had worse pain. I think most people are experiencing relief so give it a shot; it just didn't help me."

Mucinex (guaifenesin) for Fibromyalgia "I found tremendous relief during the past six months with Mucinex for fibromyalgia, however I was wondering if any other person thought that the Mucinex also caused sensitivity to sugar. I also noticed that when I took the 1200mg of 12 hour timed release Mucinex I felt energetic, however my joints were extremely painful. My shoulders and left knee were on fire, and my left leg was swollen. I reduced the dosage to 600mg timed release. Now I feel okay, able to function without the extreme pain and swelling, the sensitivity to sugar is still there though. Also, I am premenopausal and was wondering if anyone thought that taking Mucinex made the symptoms worse. Overall Mucinex works for me."

Mucinex (guaifenesin) "Absolutely terrible medication. Took it one time, only one pill, for a cold and had a severe reaction that has put me in the hospital multiple times. Had severe panic attacks, tremors, the feeling of doom, severe burning throughout my entire body, high blood pressure, and heart palpitations, and felt like I was going to die. I was afraid to sleep. It's been almost 3 months since I last took this medication, and I haven't been right since. It messed with my neurological system and my nervous system. I've been constantly worried about my health ever since. I've seen so many other reviews of people having the same experience. My doctors had no idea what was going on with me, but I knew instantly right after taking this medication that something wasn't right. I can't believe this stuff is legal. Please beware of this medication, especially if you're sensitive to it, and really do your research before trying it. I would rather deal with the cold symptoms than be put through hell like I have been on this stuff."

Be patient and pay attention to how you feel and will know if you are blocking. Dosage amount was obvious for me and I continue to get better."

For Fibromyalgia "I didn’t read about it first. I took Guaifenesin for a cold and I started feeling so much better about my fibromyalgia pain. Then I researched about it. Guaifenesin kind of cleanses the tips of the nerves and releases the knots. I felt the relieve immediately but other people say it takes time. It’s great."

For Fibromyalgia "Following 6 months of chronic pain and fatigue, I was finally diagnosed with Fibromyalgia in September 2017. I'm a 19 year old male. I was bed ridden and felt my life was over. I found the Guaifenesin Protocol after many hours of Google Research. It works exactly as it says. I was completely pain and fatigue free for 3 days after the 4th day of taking it. I spiralled back into it until about a week ago. I am completely pain and fatigue free. I'm getting my life back. Thank goodness for Dr. St. Armand's Protocol. It seriously works!"

Mucinex (guaifenesin) for Bronchitis "I began a cough 4 weeks ago. Then the mucus started. Couldn't get it up. Pharmacy suggested Robitussin which worked ok, but still needed stronger meds. Dr. Put me on steriods and antibiotics. Still mucus choking me. Tried Musinex 600. Nothing. Made me worse. The coughing started and was horrible for about an hour. I stopped using Mucinex went back to Robitussin. This drug is not for everyone. Would not recommend."

Mucinex (guaifenesin) for Cough "I had a Cough, runny nose, allergies, Then lungs got congested and major wheezing. Normally I will just take cetirizine when its allergy season, but this time my chest was in play. I looked all over the house for my bottle of Mucinex. Couldn't find it. I suffered for a couple of days with a nasty cough and gook in my lungs trying to sleep and make it through the day. After realizing I left it at our 2nd home I headed for the store. Bought the 1200mg time release (1st time), usually, I would get the 600mg. Within an hour the wheezing stopped. I am writing this comment because it works fabulously for me. I have told many of my friends and it has worked for them. Not one complaint. When I have chest congestion I will always take Mucinex. It truly works. For those that say it doesn't work, I find that hard to believe."
