Try not to get too reliant on the inhaler. I take one puff as opposed to the regular two when my asthma flares up. Of course, take the recommended two if you need to!
Seconded on removing gluten/dairy. I know some people who have had great success managing their asthma that way. Unfortunately, it does not work for me.
Try an air purifier in your bedroom while you sleep.
Stumbled into Primal due to food allergies, and subsequent elimination of non-primal foods.
