Hi Phil,pleased your choice of solution to our problem has worked for you,you would have thought that there would be some sort of spray or mouth rinse to help prevent dryness by now,but then again we seem to struggle to obtain something as simple as a nasal lubricant,or moisture maker to keep our nasals neutraly moist,I mostly use e45 cream on cotton wool,it works for me 75% of the time making the mucus more able to be got out without starting a major one.( a lady in the states uses preparation H in her nose and has done for quite some time),and swears by it.
I must admit to being a bit of a ludite when it comes to grafts and the like,heard to many failure stories for me to participate in anything that ambitious.
But that said I have tried most of the options to no avail,many times over.
Nice to chat phil.
take care Bob.........
