I had 42 radiation treatments with amofostine 20 mins. before each one via an IV.I also vomited before rad ,after rad,and throughout the rest of the day.Nothing they gave me really prevented it.I was also receiving cisplatin once a week.ALtho I didn't have much salivia[not counting that mucous stuff] at first,now 13 months out I am really pleased.I still carry my water bottle I almost never really dry out.So despite the vomit,nausea,and several in-hospital treatments for dehydration I'm very happy I endured.I'd recommend giving it a chance.
