I tried to cut down on my Advair usage because it's so darned expensive - close to $200 a month. I only did one puff in the morning. I continued taking my Singulair as prescribed, once a day, at night. I had to go back to using Advair twice a day when I found I couldn't walk up two flights of stairs without difficulty breathing. But the thing that I hate the most is the coughing and the yellow mucus. Does anyone have this problem? I breathe better after expelling the mucus but sometimes it's so hard to do, I have actually coughed up blood. I have, also, lost my regular voice. At times I sound completely hoarse, and forget about singing, That's gone. I ask the pharmaceutical companies, if I must continue taking these drugs, can you make a version I can afford!
