Thank you for your reply. I have been reading and studying this out trying to decide what to do next. I think I am ready to focus on the tapeworms. What kills the big ones? A year or more on albandazole? I'll try the low doses and see how it goes. You mentioned taking it a 6pm. So just a single dose per day? mattk3 , mentions a 3939 dosing. Should I start with low doses of albendazole on that schedule and add praziquantel? I've read through his document once, but I think it going to require a much more thorough study in order to come up with a game plan.
