The asthma situation is less encouraging. I'm still coughing every day. For the most part, it's productive coughing, i.e. once the obstruction is cleared I stop, as opposed to the ticklish cough that keeps me up all night, but I can't do things that require me to expel large amounts of breath, like laughing or singing, without starting to hack. The Advair doesn't seem to be helping much, despite being at the highest allowable dosage, so he's having me take a pulmonary function test to see if I actually have asthma. I'll try to schedule it for the week I'm taking off prior to leaving for the F2F in May.
He did suggest that I check the A/C system of the truck for mold, because I mentioned that I always seem to cough when I'm driving. I'll check it, although he also said that the levels of allergens in my blood are normal, which sort of argues against there being a point source for my problems. This does have me worried. I really would like to be able to laugh out loud again with no consequences.
Fun asthma fact: It turns out caffeine is used an anti-asthmatic in places where there is no access to things like Flovent and such. Which means I can get totally wired every day and claim it's for my health. Woo!
