I came off cold turkey too. It wasn't as bad as i expected. I was 61, so maybe had got further through menopause. But since starting Aromatase Inhibitors, I have hot flushes again. some weeks are better than others. There are a few drug options if you are going down that path. Not everything works for everyone. I have continued throughout with vaginal estrogen. This isn't recommended for everyone, but there was a discussion with my Gynecologist, Breast Surgeon and Oncologist and me. Our vaginas can get dry and fragile with age and AI drugs. I don't know if this helps. Are you having any other treatment for your BC?
