This is when I was on two doses of my medication. This is when the side effects started. The first side effect was loss of emotion, I wouldn't feel anything if something bad were to happen, I wouldn't feel sad, or mad, I would feel nothing. The second and the most effective side effect was loss of appetite. The first two weeks I only ate two things a day. I never wanted to eat at family dinners. I lost 20 pounds in the first three weeks of the month.
