I'm from Canada as well, from Winnipeg. I started taking camzyos about 6 weeks ago and I'm quite delighted and surprised that I'm noticing a difference - my gradient has gone from 80 to 30 and I'm finding I have more stamina than I've had in a very long time. Long staircases and uphill are still a challenge but I'm now optimistic that I'll be doing better at some point.
We're visiting in Vancouver right now so I'll see if there's a difference walking around the streets here from when I was last here and having to stop every half block to catch my breath.
