Hi Maeg. The first step is probably to attend an info session. I was able to do one online, which was convenient. Then I met with my surgeon to discuss options. Next was a slew of appointments and tests (psych, nutritionist, pulmonary, endocrinologist, cardiologist, sleep study, endoscopy, etc). I was not required to do a 6 month supervised diet like some others here. I would say read read read. I did a ton of research and I really feel like I'm going into this with my eyes open knowing what to expect (as much as possible.) My surgery is next week! Good luck.
