A few weeks ago I was actively questioning others in this group about their experiences with drugs other than Anastrozole. I've been on it for 14 months and really disliking the side effects. After reading responses here about Tomoxifen , Letrozole, etc., I've decided to stick with anastrozole. I've read that it is one of the most reliable at preventing recurrences, and my Oncologist agreed. My symptoms FINALLY seem to be lessening, and from what I've read here, all the other options carry the same kinds of side effects.
