I know what you mean! I wouldn't take any nutritional advice expect from a dietician. A pharmacist can tell you about drug interactions. But on a purely personal level, I do what I enjoy! I'm 71, diagnosed with a rare breast cancer almost three years ago. My basic life style was healthy, and I decided not to get stricter about anything. People talk about quality of life and for me that is about enjoying my world and the people in it. I take my meds, I see my doctors, and I do what I enjoy whenever possible. I think it is fine to make positive changes, but I am not adding any strict lifestyle regimes (although I do know folks who have benefitted--just a personal approach). I've also found it all easier to manage than initially. Have good vacation!
