I'm still on diet

So I’ve been on this diet for two weeks and have lost 3 pounds already. The result was okey. I lose some “belly bulge”, I can wear my old jeans again. Yipee! However, I’ll be much happier if I will lose more weight much faster. I’ve been dieting for two weeks now and I can’t seem to whittle down to my desire size, I need to lose more fats faster. A friend told me that a combination of exercise and some diet pills will do the job faster. So right now I’m on the search of safe and effective diet pill for women that work fast. Can you suggest one?
