My Husband And I Have Flu/or Cold And Although We

My husband and I have flu/or cold and although we are feeling a bit better, he is having trouble clearing his lungs when we wakes up. The flem seems so thick, it takes a big effort for him to cough it up and it takes him a half hour of coughing to get results. We have tried rubbing chest before bed, cold/cough medicines, drinking hot water numerous times during the day, etc. It even wakes him up every night once or twice/ Tried a hot bath in hot tub a half hour before bed. Even though he seems to improve as day goes on, every night/morning its same repeat. This has been going on for almost 2 weeks. Thanks for your imput.
