Asthma folks: what is the lowest dose regimen you've done well by and what other things do you do to keep the Asthma-monkey off your back?

Well this is kind of a no brainer, but my asthma has been significantly less prevalent since I stopped smoking/vaping weed. I have exercise induced asthma, and when I smoked or vaped every day, any amount of physical activity could potentially set it off. Now, it only ever bothers me if I perform intense cardio physical activity particularly in the cold, so I just avoid that as much as I can
