My boyfriend uses 4 Way nasal spray (phenylephrine HCl) several times a day and has been

using it for a long time, probably years.  He has developed a hypersensitive sense of smell that bothers him and triggers migraines, congestion and irritated eyes.  I am trying to convince him that he needs to stop the 4 Way, and maybe just use saline spray and Nasonex.  Currently he is using Nasonex, Clarinex D12, and OTC eye drops for allergies.  He has been tested for allergies twice and was told that he has non-allergic rhinitis and a hyper sense of smell, the nose of a hound dog.  It is often times miserable to leave his home because perfume and fabric softener are everywhere.  He gets a lot of migraines and treats them with Treximet or Maxalt.  What is your advice.  Thank you so much.
