Louise2 / theJesus, I feel you both. I've been reading this thread for a while now and decided to register and post. I, like you, have this same problem. I've noticed it, or should I say noticed others noticing it, for about 6 years now. I've tried everything, trioral, pills, etc. I see my tongue is coated a lot of the times also, scrapers just don't seem to remove it all and it comes back rather quickly. I did have a bit of luck with 'flonase' a week or so ago, had it perscribed for my sinuses and it cleared up my tongue in a day or two (I thought this was the miracle cure I've been looking for). However this was short lived, and a few days later it didn't have any affect on clearing my coated tongue, and my sinuses still always have one side clogged. Here's what I've been trying the last few days, I've been cleaning my sinuses with mild salt water rinse and eating avocados. I read somewhere about avocados are great for clearing a coated tongue, and the sinus wash if for post nasal drip. Neither seem to be working though. I really don't know what else to try, but hopefully someone will have some luck.
