Like madeler22, I am also almost 2 months in and so far so good! I take my pill in the morning with breakfast and calcium supplements (Citracal, K2, D3, B12, Mag). I then walk and a bit later I often go to the gym for weight bearing exercise and yoga. That and a changed diet to basically vegetarianism following the anticancer diet (Anticancer: A New Way of Life by David Servan-Schreiber) and keeping within normal BMI may have a bearing on the lack of negative side effects. Time will tell, as well as the next dexascan and blood work. Best wishes to all breast cancer patients!
