New to Mayo Bariatric Group: What are your tips for success?

Hi! I’m just beginning the 6 month program for the Roux en Y Gastric Bypass and was hoping to learn more from others that have done the program and gone through it and what the thoughts are and health changes since the surgery was completed.
I may end up with the Sleeve due to scar tissue but won’t know until surgery time … so info on that would be appreciated as well!
