My lungs are fine, too, so I've officially avoided the "asthma" label even though they keep loading me up with asthma drugs.

Basically pregnancy hormones gave me the constant post nasal drip, which turned into a constant cough, which turned into a reactive airway, which, after a couple of months, apparently turned into a very reactive/cranky/miserable airway and ended up into the same "asthma-like" issues. To get it under control, we used a cough med with codeine, albuterol, Singulair, and Simbicort just to get back to square 1 (and keep in mind that at that point, my DD was 3 months old and I'd been coughing to the point of vomiting since pregnancy). Apparently I'd cough enough to get my respiratory track inflamed, then I'd keep coughing and damage the already inflamed tissue. NOT my smartest move.

Since that phase, I've gotten other little colds, etc. that turn into downright misery due to this stupid cough which I'm now stuck with forever, and I've been to a number of specialists who have confirmed that my airway is hypersensitive but my lungs are perfect (and that this isn't related to my allergy history or true asthma). So honestly, I have no qualms about using the inhaler, especially now that I understand that my oxygen was low all that time and I didn't even know it. And honestly, I've huffed my vaporizer for hours, and while it might have been great for my face it did nothing for my cough. This is just one area where steam ain't gonna cut it!
Now that I'm pregnant, there is basically nothing I can do for colds, congestion, etc., so I'm using my inhaler a lot more. But breathing is kinda important, so I don't think twice about it.
