It sounds like this medication is right for you. I have the same condition as you. Do you have mucus buildup or coughing? It seems most of the medications are ment to loosen this up. I have never had any coughing or mucus; I’m not sure why. I have tried two types of bronchodilator's neither has helped open up my lungs nor does the rescue inhaler. It seems like with all the smoking I did I would have lots, I asked my doctor if they could clean out my lungs but he said no. I think it would. I just need something to open my lungs up it sounds like you had that experience the first time you tried this medication. Others say it took over a month to feel any good from it. Most just quit after a few weeks with no results. Your the first I read that had this type of reaction with the first use. Let us know if you continue to see good things.
