I've been on this site seeking help too. very few people actually responded to report their experience and its' a shame. I finished the 10 day cocktail treatment over a month ago. I ended up in the ER on the 10th day as a result of the meds. a month and a bit later i took two stool tests the results were POSITIVE!! the cocktail treatment did NOT work for me. This bug seems to be quite tricky and beating it may require a different treatment- or, as many will tell you- you may have to live with it for the rest of your life...
I'm in the same place as you. my symptoms have only worsened. Am not sure what to do next but my inclination is to try an alternative treatment. it may be a long battle but the idea is to strengthen my immune system and my digestive tract so it can rid itself of the parasite.
not sure it will work
