Since beginning SI’s program, I have gone from a size 14 to a size 8 for the first time in 15 years. I have bought a swimming suit. I know I have to do my part, but with SI Weight Loss Clinic’s help I have more self-confidence and much happier with the way I look. My husband has noticed the changes too!!! Thank you!
