I have EIA but haven't had an attack in years, I still keep my inhaler prescriptions current though because the time I'll really need one will be the time I won't have one. Your symptoms don't sound that simliar to mine in regards to EIA but I know everyone is different and I'm definitely not an astma expert. Things that I've changed that seemed to help me are that I eat more paloe-ish than I used to, fish oil, and watching out for triggers.
Have you ever had a pulmonary function test? Any types of scans? Not to be an alarmist but getting a tightness in the chest after every workout I did would be of some concern to me.
In regards to ACV I prefer to throw some in water, it doesn't matter which you do as long as you can stomach a tablespoon of it.

Pain is your companion, don't go hide from it."
