I started to feel anxious, angry and disoriented. Also experienced muscle pain. Tried to keep taking it to get ride of Babesia but just couldn't keep going. Took four pills in a two week period. Still feeling many of the side effects but the anger and disorientation have slowly subsided after I stopped taking it. Scary, horrible feeling knowing I was becoming a different person, that my personality was changing. I was watching my personality change and couldn't influence it. I would never take this drug again.
