Mucinex D Maximum Strength
"I've had pretty bad sinus congestion start and bronchitis is going around my family so I immediately got on Mucinex. The regular Mucinex wasn't doing anything for me (blue box). I bought the maximum strength D and it's been a game changer. I can breath through my nose and I don't feel plugged up at all. I had no trouble sleeping last night BUT I also have to take Melatonin to sleep every night so maybe it off set the jitters some people report. I'm very happy with it. I will keep taking until this is gone."
