Hi I ve been on 10 mg of Prozac because of migraine headaches, and my cycles are 14 days in a month which causes more migraines before taking Prozac. Being on the drug for 5 months , did give me no dought in loosing excessive weight but know gaining more water weight on top of muscle mass. A difference is to be seen when I have 98 percent of muscle than fat before having to go on this pill. Tell me is this a safe product to live by when I exercise excessively and know my weight was 117 throughout my life no less and no more.
