I found a fascinating website regarding asthma. You can find it at http://www.asthme-reality.com.
There is a method to stop an asthma attack without drugs. I've tried it on my son and it works! I have no affiliation with the website. They claim a 90% success in treating asthma. (I know your BS shield is up.) You will be able to tell by looking at your chest structure if if you are suitable for treatment.
