My anecdote: similar to you, but still allergic to cats. I have asthma attacks in the middle of the night if she curls up on my pillow, I have antihistamine eyedrops at hand, and not even my ADHD-brain dares to forget to take meds.
I've moved and gone on various diets and nothing really did anything. I give myself another year or two before I look into allergy shots (at the moment, trying to get pregnant and my allergist refuses to start them). It's rather frustrating, but oh well.
What kind of cat do you? Mine a persian with long hair and I groom him every day (10 minutes with a metal comb) so he leave less furr around the flat.
The bedroom is the only room he's not allowed, although sometimes he does manage to sneak in. On those occasions I'll probably change the bedding just to be safe.
