Hi Again

I'm kind of new to this computer and forum, so bear with me.
My son scott has been on here recently explaining my Dx.
I have a squamous cell on the base of my tongue. Stage IV T2N2B.
I am to start treatment in 2 wks. The first wk with chemo/rad using cisplatin the 1st day and then 5fu the other days.
After reading about cisplatin's side effects, I'm real concerned about using it verus carboplatin.
I am also along with the chemo/rad, going to take a supplement called protocell that was recommened by a bio-chemist friend. It is a very strong anti-oxidant. I read about this product in a book called " Out Smart You Cancer". There is a web site by the same name.
Has anyone had experience with supplements and how do you feel about cisplatin?
