Good Advice you posted Mongotu.
Your right re each attack can cause more damage.
In the ER we sometimes have to give back to back albuterol nebs plus IV meds so if you can keep the asthma under control, you are doing the right thing.
If you feel you need to go to ER just go, no one will be turned away in the USA if they present to the asking to be seen.
