Chelee,
I think the taste in your mouth might be the benadryl before the Herceptin infusion. I remember that everytime they would push that through, instantly i would taste it. Chemo is so hard to predict. your side effects might be due to all of them together. But they say that they work better when given together, so it's a catch 22. I refused the benadryl after several Herceptin infusions, due to the taste thing. The taxotere is giving you the achy problem. That does get better. I think the weekly infusions of herceptin would probably be easier, due to the lower dose you would have to get. But the dr's have the final decision. If you have any other specific questions, feel free to email me. I'm a RN so i can try to help you.
