Hi there @8leonard. I'm so glad you found the Camzyos support group here on Mayo Connect. I can't speak to your comment about starting Camzyos and now having insomnia, but maybe someone else in this group will respond in time. There seems to be wide range of experiences people have while taking this new drug. When did you learn you had HOCM? Were you diagnosed with any other heart issues before HOCM was found to be the culprit?
