The prospect of taking medication, with possible side effects, over a long period is of course daunting. So is cancer. You can of course decide not to take the medication, but you are wise in seeking very clear and precise information from others as to whether healthy living and exercise isn't enough.
Clearly medical specialists don't think so.
One option is to start and see how you go. I have been on Arimidex and Femara for nearly three years. I have one side effect only (vaginal dryness). I manage it. I have not decided to discontinue the medication as I think it may be worth the negatives.
As you get further away from chemo and surgery, you can get a better perspective on "normal". It can be different, but different may not necessarily be bad. Good luck with whatever you decide.
