Lung Cancer Chemo with Erbitux + Taxol

My father is stage 4 lung cancer patient. He had few chemos which didnt work. Then he was put on gefitinib tablets. He was fine these many days (14 months). Suddenly he started falling ill again. Doctor said gefitinib is not working and there is only very few options which might work for him. He has just started chemo with Erbitux + Taxol. It is too costly for us to afford. Doctor is also not sure how effective it will be for my dad. Has anyone here had this chemo and if yes, can you share with me your experience.

I love my DAD so much and i cant even imagine days without him..
