Betty-
I was on just xeloda, and then tykerb/xeloda, for about 15 months, and had initial great results.
Go to
www.xeloda.com and they have a treatment plan and diary with great suggestions. Be on top of your symptoms, because the H/F can be painful, and your onc will be able to reduce dosages, as was done for me several times...
Pill form was a great bonus; I just went in every 6 weeks, and then 12, for my CT scan and echo and blood work.
Good luck with it,
