DID ANYONE ELSE GET THIS WITH THIER TREATMENT

I received 39 radiation treatments for neck cancer. However, 30 mins. prior to each treatment I got a shot of ETHYOL AMIFOSTINE(sp?) to protect my salivary glands. My question is has anyone else outthere who had radiation had the shots of ETHYOL? And have you noticed a big difference with your salivary glands.
