Thanks, Sharkman, for posting these articles. I don't know how you do it! You're a better researcher than I am.
I feel more comfortable regarding the safety of fenbendazole now since research shows few side effects.
I also realize for CNS (central nervous system) treatments, a much higher dose is required. This probably explains why a double dose for 5 days worked for me better than a single dose for 5 days. Improvements noted in fewer memory lapses and improved vision.
