Question?

Hi:

My mother has been undergoing chemo with Taxotere and Herceptin on a weekly basis for the past 5 weeks...In the last three weeks she has lost about 7 pounds...is this normal? Is this because of the treament or because of the disease? I must mention that my mother is eating less, because of nausea, not being able to taste anything, depression etc...additionally my mother who has never slept more than 5 hours a day is now sleeping more than 8 hours daily...

Pls let me know if anyone has had similar symptoms and if you know what might b causing this.

Thanks

Shahyan
