I had this prior to surgery and STILL have it now...the taste I have in my mouth is sometimes metallic, sometimes salty (already had this checked out and it's NOT a CSF leak) and sometimes I have no taste at all! The worst is when it tastes like something died in my mouth! I was told it might take some time (this is a familiar response to many of my inquiries) for this to correct itself, if it corrects itself at all. This has been a major struggle for me as I really LIKE food and nothing seems to taste how I remember! I've gained weight because I find myself eating, eating, eating in hopes that I can find something that tastes good to me!
One thing I've found that helps a little is to drink lots of water, use sugarless mints, chew sugarless gum (I know it's a no-no for those of us with recovering facial nerves but....). It's doesn't totally solve the problem but it helps to mask the bad tastes a bit. It has also help me with my dental health as well. I found that I was brushing my teeth too often and too vigorously (trying to get that taste OUT!) and was starting to have some significant "oral" problems.
Anybody else have any suggestions on how to deal with this?
