My personal opinion is unless you have a documented metabolic problem like diabetes or hypothyroidism, diet and exercise is enough. The pills are a crutch, you don't need them. They might speed up the process, but are you going to take them forever? What happens when you stop?
For me 1 to 2 cups of coffee in the morning helps to control my appetite as effectively as any of the pills I've tried, but without the jittery feeling. If you read the bottles, most of them are just vitamins and caffeine anyway.
If I keep starting over, eventually it will stick, right?
