I have sports induced and mild hay fever related asthma. I take albuterol as needed and advair during the fall. When I got my student pilot cert the AME said that the FAA may want more information, I never heard a thing. On my medical paperwork now I just list it as "Previously Reported" and haven't had any issues, but I have been going to an AME that is very proactive if there are any issues. He retired this year so I have to find another good one. A good AME is worth a drive if they make your life easier.
Just find a good AME that will work with you without charging extra if the FAA wants info. Check out docterrell.com. He had some good information and has a list of the best AMEs. I'm typing this on my iphone and I am sorry for any mistakes or if it doesn't make sense.
