My doctor has prescribed 1mg of Climagest to try for three months. I wasn't blood tested. I have trouble sleeping and do get mood swings. I don't suffer any other symptoms such as hot flushes. I haven't had a period for, maybe, six months. After reading of the side effects, I am worried about taking it. I don't really want to have periods again, but wonder if anyone thinks it will help with my sleeping problems and lack of energy. I am 54 years of age. Thanks.
