By the way, I do DE + Vitamin C (sodium ascorbate) + MSM on an empty stomach.
MSM, according to ICU's topical protocol, is beneficial because it inhibits parasite's ability to stick to your intestinal walls.
Just something to add to your regimen. It is pretty cheap. I recommend getting the actual powder which is pure MSM. No capsules, no fillers etc. 1/4 tsp gives about 1 g of MSM. It tastes a little bitter but as soon as it hits saliva, it gives a cooling effect.
