I'm curious about something. I am not losing any weight at all. I have taken it for almost 2 years. I have however taken it in the past (same dose ) and lost significant amounts of weight. Probably 20-25 pounds and I'm not an overweight person. I had to stop the medication the first time. (For another reason) I gained the weight back while I was off of it but when I started again I never lost any again. Anyone have thoughts? Thanks...
