Last week I was started on .625 Premarin and 100mg of progesterone. I had a full hysterectomy in 2012 and was on hormones for 2 years and took myself off I regret it because now I have been suffering from insomnia for 3 months. I am 45 years old so I guess I'm going through menopause which I didn't think since I had my ovaries and uterus removed. Doctor wanted to get me back on the hormones when will this help me with my sleep? I have not experience hot flashes or really any symptoms except insomnia, anxiety and mood swings. The doctor gave me the progesterone to help with sleep but since I've only been on it for a week hasn't done much except make me dizzy and a little tired. I sometimes have to take a sleeping pill to help me fall asleep if that's the biggest problem but even then I take this pill I still wake up in the middle of night and hard time falling back to sleep. When will this end?
