Hi, I m Nancy. I have just gone through a rough year (divorce, breast cancer w/chemo and radiation, house foreclosure, etc) and my doctor put me on effexor for menopause issues and depression and now I have gained almost 20 pounds and I don t understand why. Maybe because I feel too tired to exercise like I use to but not sure. I do feel very tired all the time. My question is, what can I do to gain more energy and lose this weight?
