As said by a few others this is going to be a lifelong journey. I had 18 months of fighting with Aetna to get approved and had time to deal with my relationship with food. I went past the one required one psych visit and spent months talking about the changes I needed to make and how my life would change as a result of wls surgery.
I knew that the days of finishing everything on my plate when I went out to eat were over and good riddance. I did not binge eat and have multiple slices of pizza or large quantities of other fattening foods. My wife and I traveled the world extensively for business and pleasure, and ate at Michelin starred restaurants from of the best chefs in the world. My wife is thin and never gained more than 20 pounds which she quickly lost, but I gained more and did not lose.
I have lost and gained 50-100lbs many times through exercise and diet but always gained it back, due to work schedules or injury. I implore all waiting for approval or scheduled for surgery to deal with your respective food issues. Yes, surgery is scary but this one can save your life. I have had several surgeries in the last 6 years and am facing yet another, and get nervous each time but do it because it is necessary. Have the surgery for yourself and for your family or significant other. I cheated my wife and family out of several experiences in the Caribbean and other places because I was so heavy and she didn't want me to be uncomfortable. Do your research so you know all you need to about the surgery and make sure you have the best surgeon possible.
I am now 6 months post-op and at age 52 and 86lbs lighter. My wife and I are now doing things that we could never imagine before. I still have a bit to lose, but I am well on my way. Now, I need to find a way to stop my wife for shopping for me now that I can fit in regular size clothes. No matter what you decide I wish you well and good luck on your respective journeys.
