The best decision I ever made was having surgery at Mexicali Bariatric Center in Mexico with Dr. Wilhelmy. While it’s not the cheapest option, the quality of care was truly first-class from start to finish. I recommend SADI surgery for anyone who has struggled as a lifelong overeater or heavy binge eater—you will be glad you did it. It’s been three years since my procedure, and I’ve successfully maintained a 200-pound weight loss.
