What else can I can do for chest congestion if nothing I try seems to work? I was able to get two more weeks worth of singulair samples and took one last night and today. I had taken my last dose Friday before I got the samples. I've taken a cough suppressant/decongestant (mucus and phlegm) medicine, extra symbicort and ventolin. The later it gets the more chest congestion builds up. I'm not sure what else to do. It's too early to take more cough medicine since it's 2 tablespoons every 6 hours. I have two hours left before I can take it again.
