Review: One Tablet Lasted 24 Hours! - Years ago I seem to remember a kind pharmacist telling me that I should get a cough syrup with Guaifenesin in it because that would help clear my ears when they got blocked up. I tried it, it worked, I was a believer. Now I have seen the benefits of Guaifenesin when dealing with thick green mucous that was blocking up my nasal passages and lungs. I really got hit hard this year after not being sick since 2020! Whatever is out there now if way more virulent and I was at the point where I was choking every time I was drinking water and this was making me throw up. So I could not drink water easily, I did not feel like eating and basically I was quite sick. Then yesterday I took ONE tablet of Mucinex 12 hour extended release tablets and the results were amazing. Today I do not have the green mucus and my lungs are nearly all clear and I have no more sinus blockage. Basically I can breathe again without feeling like I'm going to cough too much. I am still coughing a little and that is subsiding. I am just interested to know that a 12 hour tablet could have effects for a good 24 hours. I did feel really sleepy last night when I would wake up so it may cause some drowsiness. Usually I can wake up, do things and then go back to bed. So the duration for my body chemistry was 24 hours. I think this is a great value since a few tablets are probably going to solve your issues. Please consult with a doctor if you have any concerns. I am not a doctor so this review is not medical advice. I'm just glad to be alive and happier than yesterday! I can breathe through my nose again fine without using a serious decongestant besides a nasal spray. I knew Guaifenesin was good for draining ears but I had no idea it was good for getting mucus out of lungs and nasal passages. Happy to have this new information! ~The Rebecca Review
