Go talk to your OSO. I got my air contract today, and the OSO was telling me about all the different waivers people get from day to day. People are even getting waivers for not scoring well enough on the ASTB. Also were you diagnosed with ADD, or just prescribed Riddlin, because that could make a difference. As for asthma based on my experience at MEPS I think it is a big no no, if you don't have symptoms anymore I think silence on the subject would be your friend.
