Is anyone taking oral GW572016?

I am currently in my 11 month of taking Lapatinib GW572016 (plus Herceptin weekly and Zometa monthly). Lapatinib and Herceptin have kept my bc stable.
Herceptin wasn't able to hold things down alone.
I have to medicate for "itchiness", have some blemish problems, & diarrhea as side effects. Seems like hair is "weak" and can fall out/break easily.
I am in phase I of the GW572016, taking 3 pills a day (750mg), and getting treatment at IU Med Center, Indianapolis, IN., Dr Kathy Miller.
