Sorry it's been so long since I've logged onto this site; my son has our computer for college and since we're still rebuilding from Katrina, can't afford to buy another one at this time for home. Will try to get to library more often. I'm a respiratory therapist and I don't mind answering any questions (I will check postings on Mondays and reply at the same time) and will be happy to direct you to other educational info.
What you're experiencing is called Adult Onset Asthma which is caused by several conditions including reflux. Controlling the reflux will inturn control the asthma. One med which is very good is Spiriva ... about the same components of Atrovent ... and you only have to take once a day (best time is in the morning). It's a long acting bronchodilator.
Hope this info helps. Info meant for educational purposes only and not as medical advice.
