It seemed to calm the coughing and thin the mucous, but I actually had a better experience with the nock off from Walgreens, that also had a decongestant for the sinuses. I never had trouble holding my urine, but on Mucinex I would drip when I coughed. I am also constantly burping and have pain in my upper stomach, bad gas. I haven't taken it for at least 24 hours now but still have the burping and gas pains. Mucinex was the only thing I was taking other than a few aspirin.
