In 2012 I was 39 and had a hysterectomy ovaries removed. My Dr put me on premarin and said he wanted me on it for 10 years. I took it for only 2 and quit. I don't know why. I hadn't had any problems until a few months ago. Insomnia is bad, sweats at night, anxiety, moodiness and low depression. Now I'm wanting to see about getting back on it. I'm 45 now. Any advise? Has anyone done this?
