No, ironically despite all my perimenopausal struggles, my immunity has never been stronger. I haven't been sick in ages! (In fact, my next story on Medium is going to be about that very subject.) I definitely have burning mouth syndrome, which up to 20% of perimenopausal/menopausal women will experience. I'd never even heard of it before! But the estrogen seems to be working - my sense of taste improves daily! Many thanks for reading and responding!
