First off, Fenbendazole has some neurological effects itself. I read that before I started taking it. It is the reason it is not approved for human use. But, it's a risk trade off. I take it anyway.
Secondly, and most importantly, you need to get some serrapeptase as soon as possible. This is made from silkworms and is the enzyme they use to dissolve their own silk. Taken orally it dissolves the crap in your body that blocks veins and arteries.
I've been taking it for quit a while now and have had no negative side effects. You have to start slow but as you build up it will help break down the dead worms
Thirdly, I think you might want to try pulsing Albendazole. Although it also can have side effects it appears to work better than the Fenbendazole on the eye worms.
