For Fibromyalgia "I'm not sure how long I've had fibromyalgia, but I'm guessing about 10 yrs. The fatigue/widespread pain and depression were so bad I couldn't stand it any longer. I had read about Mucinex online, but I couldn't fathom how this could possibly help me. One day while trying to work, I just couldn't stand it. I couldn't concentrate, much less keep my eyes open and the pain -- I couldn't move anything without the pain. So I walked across the street to the store and picked it up. I was very desperate. I was literally SO shocked by what happened. Within 30 minutes, the pain wasn't severe and for the first time since I can remember I didn't feel that debilitating fatigue. I told everyone that would listen. It's been miracle for me."

Mucinex (guaifenesin) for Fibromyalgia "I also take Mucinex and have since 2003. As I have read the reviews I have not read any mention of having to remove salicylates from all topical products. Been on Guiafenesin for 10 years and has helped me greatly. "

Mucinex (guaifenesin) for Bronchitis "I get asthma “colds” that turn into Bronchitis once a year. I find Mucinex “keeps the elephant off my chest”. And, you’ll know what that means if you’ve had bronchitis! I will take Mucinex in the morning, and feel fine most of the day, thinking I’m getting past the infection. Then WHAM! Elephant...on...chest!! Cough, cough.... Mucinex may not work for everyone, but it sure helps me breath deeper and easier!!"

Mucinex (guaifenesin) for Fibromyalgia "I have recently been diagnosed with fibromyalgia. Soon after I had a cold and started taking Mucinex to clear out my sinuses. Not only did my sinuses feel good but I noticed that in general I felt amazing. My body just didn't hurt like it had been hurting for the past few months. So I got online and typed in Mucinex... low and behold the first thing that popped up was using mucinex as a treatment for fibromyalgia ... crazy. I had no idea... so for those of you speculating that it may be a placebo effect ..believe me I felt the difference without knowing that others have used it as a therapy.... it works wonders!"

Mucinex (guaifenesin) for Fibromyalgia "I never thought that an expectorant used to treat coughs could be this effective for Fibromyalgia pain. I am a pre-med student and when I heard about the possibility of Mucinex(Guaifenesin) being able to relieve pain caused by Fibromyalgia I decided to try it. It has worked better than NSAID'S (Ibuprofen, Aleve, Celebrex) for me. 400mg works great (600mg if using the extended release tablets.)"

For Fibromyalgia "I have had fibromyalgia for most of my life. Even as a child I suffer from severe leg pain. Each time I was given guaifenesen to help ease asthma congestion I always felt better. Today I take magnesium, guaifenesen, and vitamin D1000 x 3 and I finally have my life back. I tried Lyrica which locked up my jaws. Cymbalta and many other antidepressant's to no avail. For those of you that it doesn't help perhaps you need a second opinion on your diagnosis. I have to many friends on these meds that have reclaimed their life for this treatment to NOT be on to something. Perhaps more research is needed, but why would they do that when the medical and big pharma is getting rich shoving Lyrica, Cymbalta down our throat and getting rich."

For Fibromyalgia "Mucinex (guaifenesin): "With moderate to severe fibromyalgia for 25 years, lost my career & lived in fear of having a life to avoid a flare-up mostly sleeping bedridden 75% of time. I also have polyneuropathy, trigeminal neuralgia, occipital neuralgia, severe cervical DDD, myelopathy, etc.. have tried every antidepressant, SSRI, pain medicine, anti-inflammatory..you all know, with major side effects. Feb 2016 I got a cold on top of allergies used Mucinex daily 800 mg then up to 1600 mg & could not believe the relief even at 800! I have prayed for someone to invent a NEW MEDICINE for fibromyalgia that would work..turned out this OLD MEDICINE has returned a lot of my life to me, helps the pain, brain fog, fatigue& depression too!"

For Fibromyalgia "The Guaifenesin protocol has helped me beyond all belief. Before I found Guaifenesin, I was mentally incapacitated and was ridden with pain. I experienced a neck injury by lifting my handicapped mother who has a debilitating disease. Seconds after the injury, all of my Fibromyalgia symptoms surfaced. After finding a support group, I started on Guaifenesin, the miracle drug, 6 months after my injury. Without this drug, I would not be able to live a "normal" life. I immediately started on the road to recovery. It was a slow process but gradually improved my symptoms. Now, 16 years later, I can honestly say that Guaifenesin has given me my life back."

For Fibromyalgia "I started taking guaifenesin about three weeks ago at 600 mg every morning . I had improved in most of my pain but still was getting that evening pain and so I just increased to take another 600mg in evening. I slept so deep and woke up feeling like a new person. I will continue on this because nothing else has ever helped my fibromyalgia better. I can get my life back together now."

For Fibromyalgia "I am a retired nurse. I have done all of the 'research' regarding the Guaifenesin for Fibromyalgia treatment. I was diagnosed a year ago with this painful, awful disease and am unable to tolerate any of the prescribed medication available. After a friend literally stumbled upon her Mucenex treatment - having an upper respiratory infection and her Fibro pain subsided! I started on the Guaifenesin only at 600 mg a day. Not only did my pain ease up immediately - my mucous level is lower and I am confident that this will help my C.O.P.D. because I am breathing better. (Oxygen dependent at night) This OTC treatment has relieved my pain by 80%. I am sleeping better and moving easier. This works and has changed my life and attitude."

Mucinex (guaifenesin) for Bronchitis "Mucinex worked like a charm for me. When it ran out, I made the mistake of waiting a few days before I went out and got some more!!! Since I have Chronic Bronchitis, I will always have this medicine on hand. I had to see a doctor before taking it, since I am taking other medications, and had to make sure there would not be any dangerous interactions. This medicine is a wonder drug for me. I have now quit smoking, and am using nicotine gum. If your Bronchitis is caused by smoking, you also need to quit. The nicotine gum will keep your nerves calm, and that way you won't have to quit cold turkey. When on the gum, you can take care of the psychological withdrawls, and later take care of the physical withdrawls. Not both at same time."

Mucinex (guaifenesin) for Bronchitis "Made coughing a lot easier after feeling like I was going to die from the phlegm that was blocking my air passage. I didn't give it a full 10 because it gave me a slight headache and a bit numb/tingling feeling all over my body but nothing to be alarmed about. Oh my goodness what a difference. I can breathe and finally sleep knowing I'm not going to choke to death. Thank you Mucinex."

Mucinex (guaifenesin) for Cough "After all the treatments I had from the doctor, nothing really suppressed the cough, which I have had for years. After taking Mucinex, my cough and the associated Phlegm has almost disappeared. I am a 74 yr old male but my side effects seem to be the opposite to others. i.e. I am doing more sleeping than normal, at any time night or day, but thank heavens for the cessation of cough."

Mucinex (guaifenesin) for Fibromyalgia "I started this when I was working with a patient on Mucinex therapy. It worked, but I thought it was a fluke, and I stopped taking it. Months later, stiff and unable to get around and work without severe pain in my lower back and neck, stiffness in my hips and knees, and general achiness all over, I decided to give it another shot. I have Crohn's disease which causes fibromyalgia symptoms. Since the Crohn's didn't seem to be negatively affected by the Mucinex, I started on it again last week. No pain in my lower back, still just a bit stiff in my neck. I am so happy that back pain is gone. I can do things again and not hurt. I don't have to be on narcotics and I sleep like a baby. I recommend at least trying it."

Mucinex (guaifenesin) for Bronchitis "First time Mucinex DM user. I like the extended relief because it really does provide extended relief from the severe coughing that is characteristic of bronchial infections. The medication did make me a little drowsy, so some caution is recommended especially if you are not able to take time off to rest. I also recommend drinking lots of fluid too. You may notice that your urine smells like the medication."

Mucinex (guaifenesin) for Fibromyalgia "It works. I have not had 100% relief but this is the first 4 consecutive days I have been able to go without some type of pain medicine. Neurontin worked for me as well but it made me sleepy and irritable. I'm taking a good vitamin as well but I attribute this profound relief to Mucinex- 600mg daily."

For Fibromyalgia "My teen daughters were diagnosed with Fibromyalgia before I was. I did tons of research to help them and stumbled on Dr. St. Amand's Guaifenesin Protocol as well realizing that I had a lot of the symptoms as well. We went to Marina del Rey to see the doctor himself and were diagnosed. That was over a year ago. Guaifenesin has helped us all immensely. My daughter was dancing competitively and then couldn't do anything. Now she is dancing again, getting better all the time. My youngest has had her IBS symptoms disappear! You really have to follow the protocol as written, by removing salicylate products and taking long acting guaifenesin. I suggest getting the book, "What Your Doctor May Not Tell You About Fibromyalgia." Read it to understand."

Mucinex (guaifenesin) for Fibromyalgia "I have had severe hip, lower back and leg pain lately, and have had so much pain walking, sleeping and could hardly bend. I made an appointment with my doctor and though I have fibromyalgia, I thought I was really headed for trouble. Then wham - I was hit with a bad cold. I took my hubbie's Mucinex and thought - am I imagining things or did my pain magically subside? I don't know why, but boy what a difference it made! After a second dose, I looked it up and found this post. Going to the doc's tomorrow and will tell him."

For Fibromyalgia "I've been taking Guaifenesin for 18 months, along with following all of the guidelines written by Dr. R. Paul St. Amand in his book, "What Your Doctor May Not Tell You About Fibromyalgia". Before I started the Guaifenesin Protocol, I was in so much pain, and had so much fatigue that I was in bed much of the time. Slowly and steadily, I am getting my life back. My pain is much better. The fatigue still comes and goes, but gets better each month. Some of my other Fibro symptoms are completely gone. It is VERY IMPORTANT to follow the protocol as written by Dr. St. Amand, especially avoiding plant products (salicylates) on your skin. Just taking a Guaifenesin pill will not make you better. Do your research--you can do this!"

For Fibromyalgia "My Fibro pain started 35 years ago and all the doctors shrugged their shoulders. In 2000, I was finally diagnosed and given pain and sleep medication to control the symptoms. At this point I was on the verge of a nervous breakdown. When I finally climbed out of the hole, I wasn't content with just "controlling" the symptoms with medication. Yes, it put me to sleep the 1st week and made things worse but the guaifenesin worked very gradually, and over time I began to improve. This is NOT an instant fix. or cure. It takes months and even years. Over the past 16 years I have stopped taking Guaifenesin 3 times and each time I have been slammed with pain within a few weeks. The lesson is just keep taking it."

It has been a life saver for me as I was able to get my health and stamina back in shape by closely following his instructions and recommendations. I was able to maintain my executive working position and later was able to be a caregiver for two family members. I highly recommend this drug and protocol."

For Fibromyalgia "As strange as this may sound, I have found that good old Mucinex, that is, active ingredient *guaifenesin,* really helps amazingly with my stiff and achy hip/haunch muscles, tendons, and ligaments. I suffered a very minor injury years ago, but the area around it became stiffer and more painful over time. I noticed once when I had a bad cold and was taking the usual cold remedies that my hip area felt suddenly better. I narrowed it down to the effect of guaifenesin. Since then, I have found that many fibromyalgia sufferers also report an amazingly beneficial effect of guaifenesin on their stiff muscles! It really does work, is sold over-the-counter, and I notice no side effects. They make 600mg tabs, but even 1/2 tab per day really helps me. I hope it helps you too!!"
