Clem works, with a good diet. I personally hated it, I did two weeks and couldn't wait to get off. Anxiety, sweats, dizziness, nausea. Didn't feel to good once your heart start skipping beats and your hands start trembling. These are all negative signs from the body. To me it's not worth it. Up your cardio and eat better, dropping 10 pounds in 2 weeks is unhealthy alone. Please use this drug responsibly
