Anyone ever take Navelbine with Herceptin every week?

My name is Cathy. I'm 37years old with stage iv bc and mets to my lungs - Her2+, E/P-
First let me say - I hate cancer! Ok, now with that out of the way...I've been on so many drugs and nothing seems to work. In June - Oct 2004 I did AC/and one round of Taxol. It turns out I'm allergic to Taxol and Taxatere. So, my onc. gave me 3 rounds of AC +5FU. Then, in in late Oct 05, I started Hereceptin - alone with no chemo (because I can't take the taxol). I stayed on herceptin until March 05. My onc. took me off in March because me ejection fraction was at 49%. Then in May 05 the "spot" on my lung decided to grow. Now it was big enough to biposy. Well, this whole procedure took about 6 weeks (between setting up appts with various Dr.'s). The results came in June that the "spot" was met. BC.....gee tell me something I didn't know in March. I felt we had lost 6 weeks for nothing. In June 05 I took Xeloda until early Sept 05. Well - that didn't work. The spot or "nodule" continued to grow. It was only 8 mm in size but still growth is growth. So, in Sept 05 my onc. changed the chemo AGAIN. In Late Sept 05 I started Gemzar with Avastin. Well, I just go the results of my chest CT scan last week and the Gemzar and Avastin didn't work as great as my onc. had wanted. It did shrink one nodule and kept two others at the same size and the other two grew each by about 1mm. But - good news - no new nodules detected. So.....no this Friday I'll start Nevalbine with herceptin.
I'm wondering if anyone's been on this regimin and could let me know their results.
Thanks!
