Giardia/Protoza and Berberine treatment

Hi

As some of you know I am on a quest to get well, no matter what. I have had some success so far, and am currently on Fenbendazole. However, I still see the eye floaters and the microscopic stuff floating around in my vision when I look at lights and squeeze/relax my eyes...which leads me to think I have protoza stuff too...so I researched and read about Barberine...and even garlic is supposed to be rather effective...can anyone advise?
