I lost 12 lbs over a few months and I was tracking everything i ate and getting regular exercise and really excited my efforts were paying off. Now, since i started the brand name of the generic pill i was taking I've gained 4 lbs back almost immediately within a week. I actually cut my calories a little more than usual and had got a little more exercise too. Before the pill I was eating around 1400 calories per day and since I started to feel myself gaining, I changed it to 1300, lowered my salt intake and added a little bit more walking. I'm so discouraged and I don't know what to do.
