I Have Asthma. Usually It Is Ok And I Am

I have asthma. usually it is ok and I am symptom free. Yesterday, I was walking around outside a lot and my chest got really tight, I was wheezing terribly and couldn't catch my breath. The emergency inhaler helped a lot. Today I feel better but still feel chest tightness and wiped out. this is the worst my asthma has ever been.
What home remedies, besides the inhaler, can I do to alleviate some symptoms between doctor visits. (Going to my dr this week and getting back on the meds - which I don't like taking when I don't have symptoms....)
