So sorry, Judy, that you are having to deal with this again. I don't know anything about the gemzar drug. I know everyone may have a different reaction, so you may not lose it all.
Have you been to a cancer treatment center yet? If not, I'd be looking at that. If for no other reason than to see if they would offer the same treatment.
HUGS. Please let us know how you're doing. I'll be praying for you!
