I think the idea is to get the circulation moving in your eyes (so the formula may have cayenne in it) Same thing happened to me. I started over again with less tincture in the water/eye cup. Then the effect was less dramatic. Then I gradually built up to more drops per water/eye cup. I think the highest I could tolerate was four drops. But if you build up gradually, you tolerate it better and hopefully, you get the desired result: healthier eyes and clearer vision. My eyes started feeling better but I never had a big transformation. Probably because my shoulders, neck and head are hard as a rock. Decided I should do the complete Incurables Program and get everything moving.
