Hi Sharon,
What's worked very well for me in the past (and now, I'm unfortunately having to re-do due to several physical and emotional challenges) is the following:
1. A minimum of 80-100 oz of water each day
2. An accurate journal where all calories in (listing the specific foods), calories out (listing the type of exercise), and water intake are recorded . . . I intentionally tend to overestimate calories in and underestimate calories out so I don't have any nasty surprises on the scale (oh, I also put scale readings in the journal)
3. Five evenly-spaced tiny meals each day of 300 or fewer calories (and never skipping breakfast) . . . plus, I visualize good food as fuel, never reward . . . and bad foods I try to visualize as a toxic drug, as if I was a heroin or meth addict craving them
4. A minimum of one hour of cardio every day (I treadmill with hand weights, doing arm exercises the whole time since I have floppy arms) . . . I increase this as I approach a normal BMI and weight loss slows
5. Surrounding myself with supportive and motivational people, books, and programs . . . and learning not to let the past sabotage the future, meaning that if you "slip," you simply acknowledge what you did and move on, not letting guilt or shame or any other negative emotion lead to a binge of slips . . . a 5# mistake is infinitely easier to deal with than a 50# one or a 150# one
So basically, you can eat small, frequent mini meals as if your pouch was working (protein first, followed by healthy fruits and vegetables, and nonfat/low-fat dairy if you're not lactose intolerant) while you regain your health and build your immune system through a healthy diet and exercise. Then, once you're feeling strong again, you can look at how you've been managing and then decide whether to have your surgery revised or to continue on with what you've been doing.
Anyway, hope at least some of this might be helpful to you. Just keep in mind that when you look at what works for everyone else, you will need to pick and choose the methods that will work for you personally. Your lifestyle. Your cir****tances. Your mindset.
Good luck, and I'd be glad to help in any way I could.
