My Sports Nutritionist (who I have been very happy with throughout my treatment) is highly recommending that I get some IV Vitamin based therapy to help with my recovery.  In fact he would like for me to do two treatments a week for the next two weeks.  Please note that he says this is for recovery purposes only, not to eliminate any future cancers/problems/etc.  
I just finished my last rads a week ago today.   I was one of the lucky ones as it did not hit me as hard as the vast majority.   My gut it is that much of it is due to: 
no chemo, 
the latest IMRT/IGRT kit at Sylvester, 
my physical/mental shape going into it
My diet during the treatment
plus just got lucky?
Has anyone had any experience with IV Vitamin treatments?  If so, I would appreciate your advice as well as any positive/negative experiences.
