Will MMS interfere with medications?

My daughter takes metformin, along with several nutrient supplements. Can she take MMS at the same time (assuming she isn't taking vitamin C, of course)?

How about stevia and cinnamon? They are both potent killers of bacteria; with they neutralize MMS (I know it's not a bacterium, but I'm just wondering. . .).

I am starting her on Protocol 1000--this diabetes 2 really stinks!--but am having a challenge giving it to her 8x a day, partly because of her medication schedule.
