I've got it, mate, BA know and they've given me several of the toys in the box to play with over the years. As long as it's fully controlled using one of the approved drugs (they change, I've a grandfather clause on one of the older ones!) and the symptoms are mild at the worst you should be ok.
May I suggest a search through the medical forum on here? I recall some previous threads rearing their heads on this subject.
Good luck!
