Well after talking to my E.N. T. we have both pretty much decided that what I don't have yet after nine years isn't going to come back. After a while you figure things out, like extra paper towels for that runny nose. Lots of water and maybe even some Biotene Gel. I don't think my taste or saliva will ever get better. My hair is not coming back.But like they say you learn to live with things. I think that all of us have been through so much worse these are the little things. I did get rid of my mask after about a year but kept the pictures of it on at the machine. A lot of people don't understand things and when they see a picture it tends to help them understand a little.
