Sounds like you're taking positive steps to get a handle on these unwelcome intruders. If you don't mind me asking, where did you go to school that they gave you a paracide? Now days they can't even give out an aspirin! I really wish they would at least TEACH kids about parasites and prevention.
And good for you exercising on a regular basis. If you have access to a pool you should maybe try water exercises, that would be no impact on your hips.
I use the Terramin clay mixed with water for detox and paras. I'm not sure what the real difference is between DE and Bentonite? Good luck and keep us posted on your results.
