bronchitis
"I have a very bad bout of bronchitis. I'm on day 5 and I don't feel markedly improved. The coughing is not quite as often, however when I do cough the phlegm feels thicker and the coughing spasms are more violent. It could be because the Mucinex is now wearing off. I just had higher expectations. Now I'm nervous, because I don't feel like my condition is improving. And the sound and feel of the mucus is a lot worse, but no side effects."
