Just a tip for the metallic taste that can be a result of chemo. When that happened to me, I found that sucking on honey-lemon cough drops relieved it. Weird, but it worked. I would have this taste for two or three days after chemo - until, of course, the rad fried my taste buds altogther. Completely back to normal now, never did like hot/spicey, so no change there. It just takes time. And thank goodness, chocolate still tastes good!
