Hi Cindy, thanks for replying. Where are you from in Canada. I’m from Vancouver. I’d love to find someone from around here that I could get together with. No, I’m not on any replacement medication at the moment. My eyes are my big problem. Double-vision and tearing and sensitive to light. Although at this point it is the lack of energy that bothers me most about this disease. Best of luck to you. Keep happy! SAS
