I started taking 40mg in October. I have insomnia and night sweats most nights. I get headaches if I don't eat when I take it. I have gained 24lbs since October. I work out 3-4 days a week and cut my calories to 1800. I followed this workout plan before and lost 75lbs and kept it off until now. I like the meds because they really help with keeping my emotions in check, but I want to do something about the weight gain.
