Take it with yogurt!! And yes, i understand the bugs seem to know when an attack is comming!! Very strange to say the least! Also coq-10 is the reccommended vitamin! It dbls the strength of the meds. Get the highest mg u can. 400 mg 3x a day is good. Also zinc for immune system die off with vit. C. I dont think the ivermectin alone will kill them all. U can get moxidectin with prazi in it for $14 in a horse paste tube for your next round.
