Initially I thought I felt better with the 5mg dose but now entering my fourth week taking 2.5mg I feel great. I am able to walk a few miles even in the heat (early in the morning). What I am now not feeling which I did feel with the 5mg dose is sudden fatigue to the point of quickly nodding off. For me, it seems to take about 3 weeks for the effects of each dose to be consistent. My next echo is in a week. I am hoping my LVOT is at 20 or above or there will be a lot of discussing on my part. Since this drug isn't a cure but a prevention, I would assume that being taken off this drug (if my LVOT is below 20) would put me back to where I was before Camzyos.
