cough and nasal congestion
"I currently have the flu and am taking tamiflu. My congestion and cough had me worried I would not be able to sleep so I checked to make sure there wouldn't be any issues taking the mucinex d while also taking tamiflu. I took the mucinex d at 8pm and immediately felt like I couldn't go to sleep. I sat up on the phone for 2 hours listening to a discussion trying to go to sleep. I finally did to only wake up at 2 and be in the same situation I was in before. Unable to go to sleep wide awake. Rest of the number one thing I need right now and I'm not getting it because of the mucinex d. I'm very unhappy with the drug."
