I'm sorry to hear about your father. I have an excellent doctor who specializes in cancer (nutrition/herbs/vitamins). He's in New York City. Are you close by? If so, I'll give you his information.
Here are some other message boards for you to join and post this same message to. They are very busy boards and you will probably get a lot of responses:
www.acor.org (register for the lung cancer -nsclc board)
www.lchelp.com (this is another great board with a few different headings you can post your message to (in introduction; non-small cell and general sections).
Take care.
