I was put on in after a year sober for mood swings during my cycle. I am 46 and have never tried anything like that before. I loved it. My sleep went back to normal and I felt calmer and more focused. It seemed to me it worked quickly too. I just went into the doc and I put on 20 lbs when I already needed to lose 30. It does that to some people. Taking it at night might help that. They switched me to something else but if it wasn't for the weight gain I'd still be on it.
