I am sorry to hear that you have both acid reflux and asthma.  One of my children deals with both issues as well.  She had to be placed on an asthma controlling medication, taken twice per day, and a PPI in order to get her symptoms under control.  If you are using a rescue inhaler frequently than your asthma may not be under control.  It might be a good idea to discuss the problem with your physician or a pulmonologist.  My husband just dealt with similar issues, had a lung function test and was placed on a controlling medication as well.  His breathing has improved drastically!  Best of luck to you and please let us know how things turn out!
