I am in the same position as you Pipergirl.
My asthma is very mild, well controlled and doesn't cause me any problems (unlesss theres a dog or a cat in the cockpit).
I hope to take my class 1 later this year and from what I can find out, I should be ok but I will have to get a report from my GP giving an opinion on my health. (he is a PPL too so luckily he knows exactly what I need)
I would like to know how you get on
