I am in my last year on Femara and I have had two side effects, including the wear and tear on my bone density which mercifully was really good to begin with, but no hot flushes, aches, pains or anything like that. I'm willing to put up with some side effects if it helps keep cancer at bay. If I didn't, I know how I would feel if it returned. I also understand there are no guarantees (in life generally!). It's always a personal choice, but I'd advocate for trying it first and then make a decision rather than relying on other people's reactions. Side effects are hugely variable.
