I took Aromasin (Exemestane) for about 5 months after a lumpectomy for DCIS and 5 radiation treatments. I really felt unwell on the medication. Poor sleep, mood issues, (I deal with anxiety and depression) and worried about my lack of energy, potential bone loss and lipid/cardiac issues. As my DCIS was very small and no cancerous cells found in my lumpectomy, I elected to go off it. My risk of recurrence is small in general. It was a hard decision, but I found that dealing with life in general can be hard enough some days! I try to eat better, exercise most days and work on lifestyle changes. Mammogram one year out from diagnosis was negative. We all have to decide what is best for us and our circumstances.
