Lemon in mineral water, crown mints... Some things started off okay but I list the taste for them as time went on. By the end all I could really taste was the basic sweet, bitter or salty - no actual flavour . My favourite meal during chemo was fettucine with lightly sauteed chopped cherry tomatoes and black olives in oil and garlic, topped with basil pesto. The pasta satisfied my need for carbs, and the other flavours were strong enough to override the chemo mouth for most of treatment. I did use Biotene mouthwash the whole time. I got oral thrush once and it caused more problems with taste. Check your tongue - if you're developing a thick white coating it's probably thrush which can be easily treated.
