Msm and vitamin-c

I had so much msm left at home from another treatment period that I decided to eat it up. I took 8 teaspoons a day of it as well as 8 teaspoons of vitamin-c(ascorbic acid) with it, for 3 days and it was like a war started in my intestines. The parasites were moving all around in there. I think it's mostly the msm that does it, since I used large doses of vitamin c before. Anyone else with that experience with MSM?
