Its bad news really but , I lost weight at the start of Prozac 30 years ago, its a honeymoon period. A few months in the weight will come , Prozac is working fully at this time and you get a little careless with the food , if you are happier you eat more . But Prozac like all SSRI,S change your hole body if on a year and more. like the guy who posted this gem you chose vanity or insanity.
