I've been on nose spray since I was 12, phenylephrine. I've stopped for months or occasionally years at a time, but always go back. In almost 50 years of use, the only side effects have been a slight insomnia, a tendency to get nose bleeds in a fight, and the gradual decline of my sense of smell. I can still smell bacon, diesel, and pot plants in flower. So I was super happy when the little freak show started giving off something I could detect.
Not sure about skunky, but definitely more bacon than diesel : )
