question: hello i have a bad cough and saw my internal medicine doctor today, she checked my breathing a freaked out cause of how bad i sounded, i then coughed and cleared my chest out and she checked again and i sounded great. The only problem is she gave me advair.... "doesnt work immediately she said" but i will wake up from sleeping and cough myself into a really bad pressure headache that will cause my ears to ring and cause my vision to darken off. what can i do before going to bed, or right after i wake up to break up the mucus that builds up in my chest that causes me to cough for so long.
