I used triclabendazole for 3 days after nearly 4 years of suffering with CFS. I always had vague pains in my gallbladder and spleen region. I suspected I probably had parasites. Treatment with this drug completely eradicated the nonspecific digestion pain and frequent bowel movements I was having. I also have quite a bit more energy now. I tried the other anti parasitics like albendazole and praziquantel and did not see much improvement. I'll bet I had multiple parasites. I used to eat a lot of sushi and I am guessing that is where I got them. Anyways - just thought i'd share with y'all.
