I started off with chewing gum made the mouth tingle to start with but it seems to have conditioned the mouth.
I get thru 4 or 5 packs a day but it really has made the difference in that i don't have to drink litres of water.
Mind you taste buds are weird - for lunch i had chips with salad cream in a crusty roll with strong onion and cheese (not my normal lunch).
I wonder if not having a peg during treatment made the difference. I had to start eating soon after treatment which was difficult but now I find I can eat most things, I still have ulcers but s*d 'em.
I am sure you will get back most of your "eating funtions" - you'll soon be eating hot spicey food.
