I think you are having no luck with meds because you are not absorbing anything properly. Your bacteria is all messed up. If you can look into injectable albendazole or iv treatment with vitamin c you may be able to get rid of alot of the diseminated parasites. I would also work on healing your intestines with bone broth, lglutamine, l arginine, and l ornithine. A strong probiotic 50 billion or more with a good mix will also help once your intestines start healing you will start getting stronger because you will be getting nutrition. Dont take b vitamines, avoid Sugar and dairy. Target the Ascaris first because they are the most dangerous. worry about the tape worm last.
