Oh, being colonized means you "have it" - just not at the level that is is making you ill. If you are diligent about nebbing and doing airway clearance, you may well be able to avoid having it invade enough to require antibiotic treatment.
I have a question about the levabuterol neb - do you need it to keep your asthma controlled? If not, you may get just as good a response from 2 puffs of a levalbuterol or Symbicort inhaler about 10-15 minutes before you neb. The Symbicort was a game-changer for me - total asthma control without the albuterol/levalbuterol tremors and rapid heartbeat.
