I have lost 7 lbs in a week in a half. There are side affects, but none that are different from adipex. Side effect i noticed were dry mouth, extra hot, ocassional dizziness,jittery anxious feeling, and ocassional headaches. Those are the same side effects i got from adipex. I take mines at night and wrap a band around my waist. I take it at night so i want have that jittery feeling that it gives me. I suggest it to anybody as long as you take it at night. And i think it has better results than adipex as far as losing weight.
