Thank you for all the info.  My oncologist told me that only 5% of people had a difficult time with amiphostine, but it sounds like most people do.  I'm going to give it a try with Zofran and addition fluids administered.  How do you suction while receiving treatment?  That would make all the difference I think.  And I will definately ask about the suction mouthpiece.  What is it?  The people on this forum are the best.  What a great resource to have others with experience.  Love to all of you.
