Jennifer,
I read your other post as well. I don't know anything about this
Erbitux but I know you will learn from others. I just wanted to say welcome.
I will be thinking of you and your mom on Wed. I hope you can find the answers you need here and from the Dr.
Don't give up I have read some real amazing stories here. I know someone will be able to give you some good help.
Take care,
Diane
