you should never be lying flat...those days are gone. I am surprised your dr. didn't explain this to you. Also, ask your dr about a thing called an aerobika you attach it to a breathing treatment machine and it will help you cough and clear your lungs. Look it up

@ TinaGoode Hi, the number 1 thing you WANT to do is cut down, wayyyyy down on milk!! Anything with milk or cream is going to produce mucus. Next, drink a LOT of water, water thins out mucus. Next ask your Dr if it's ok for you to take a OTC Mucinex every morning and every night. It will really help you. Good luck!

I sleep at a 45 degree angle find it helps alot

You can get a "wedge" type pillow to elevate your head when sleeping. Got mine at Amazon.

I have slept in a recliner for 18 yrs......could not sleep in bed with pillpws or wedge....smothered to death.....I just lay back in my recliner according to how bad my congestion is at the time.....good lucl....hugs.
