I had the same outbursts with Anestrozole. I was so mean. I've always been known as being too nice. My hips, feet and legs hurt. I tried every other day but my side effects were the same. I quit it for over a month and my life went back to normal!! Now I am on the AI that starts with an E. I am full of anxiety. It's such an awful feeling. I can't remember anything and I'm afraid I'm getting dementia. In the back of my mind I know it's the meds because I've only been taking it about 1 month. I can't sleep more tha 4-5 hrs per night because of the anxiety. I always feel as though I've drank 10 cups of coffee. Exemestane is the medication. I may just stop. My ILC was caught early and I insisted on a dbl mastectomy. No lymph node involvement. I wish we didn't have to go through this. Hugs to all
