If you want to pm me, i will forward your email address to someone who flew the Harrier and is now on exchange flying singleseat. He had childhood asthma and it was on his med docs before joining up - he may be able to give you some good advice as to how he got through the system.
As others have said, it is a much tougher world than it was 10 years ago, and the military can afford to be fussy... but at least you are giving it a go - good for you.
