After taking the generic for Ambien 5mg to help me sleep, I woke up with my phlegm choking me, At first I could not cough it out or swallow it down. I immediately got up and it eventually subsided. I would like to take a Mucinex DM to help. with cough and congestion.

hank you. I am so tired and want to sleep but I keep trying to cough up the phlegm
