Started with Arimidex but after 4 weeks of either diarrhea all week or constipation all week combined with fatigue & flatulence put on Femara. Femara fatigue better but upset stomach, flatulence (very stinky) and stomach always upset. Even if I cut back on eating it still there. Tried it at night but night sweats very bad. See others are bad too so considering not taking it or anything but wonder do the side effects on stomach ever subside. Flatulence very very embarassing at work.
