asthma, maintenance
"Mine is a seasonal asthma and until Symbicort I ended up in the ER several times a year (spring, summer, fall). 
That's when I take 2 puffs X 2 times a day and have yet to have an attack.  Winter, only 1 puff every other day. Sure, I have occasional wheezing, but that's why I have Ventolin.
Looking back (10 plus years), I have to tell you - I'm really happy not to have to use Prednisone, possibly ever again."
