@Caibo, someone told me fruit tingles worked for them but they didnt work for me. I just drank loads of water and brushed my teeth and tongue :D then gargled with Biotene regularly. Biotene was very refreshing and was provided free from our public hospital.
I never got rid of it completely during AC but I used to pop frozen blueberries, watemelon, grapes in my mouth and take my time swishing them around and I lived on frozen yoghurt icecreams.
The good news is that the bad taste disappeared about 2 weeks after my AC finished and I started to enjoy food and my divine cup of tea on taxol :)
Hang in there, play around with the fruits, see what you like.
