Sweets and high fat don't make every person sick after the surgery, and most of the time it is a short term effect for those that do get sick from them. I couldn't touch high sugar for about 6 months, but guess what? That effect wore off and I could eat anything now with no serious repercussions other than gaining weight. I know that, so I don't eat crap foods all the time. I do eat stuff like a cupcake or a cookie for special occasions, but I plan out my day so I know I have room in my calorie count and I eat healthy 90% of the time, so eating something "bad" occasionally doesn't derail my whole life.
Relearning how to eat healthy during the honeymoon period is what the surgery is really all about. You have to throw out everything you used to do and establish good eating habits while the restriction takes care of the Portion Control. That is what everyone is supposed to learn how to do during the honeymoon phase after surgery. It is really sad that the doctors don't explain this part better to every single patient before they have the surgery. If you don't do this, then the weight loss will happen in the beginning just because you're not able to eat as much, but likely will slow down sooner, and also regain is very likely once your metabolism adjusts in a year or two and all you still eat is crummy foods.
Anyway.
You definitely need to try doing the 5 day reset. It will help remind you how your stomach feels and feel the restriction again, and should help you detox from the sweets/crap food cravings - eating high carb usually makes you crave more carbs - it is a vicious cycle.
You made some mistakes, but the sleeve is still there, ready for you once you're ready to recommit to eating correctly. You lost the best time to make fast and easy changes, but if you put in the work, you can still make it happen. But you have to be willing to do the work.
Start tracking every bite of food and sip of drink. Get your Protein and Water goals figured out, keep your carbs low (under 100 definitely but if you can push it down to 50 grams/day that would be even better), and get your calories for the day down to around a 500 calorie less than you burn in a day.
Throw out all the junk food in your house. Tell friends and family to not tempt you with foods like that and don't go places where you'll feel weak until you get control of yourself. Think of it like being an alcoholic or trying to quit smoking. You don't go places where you'll feel tempted and you ask friends/family to be supportive of your struggle and not offer you things you shouldn't be having, and do your best to remove the temptations from your path.
Exercise - find something you enjoy doing and then do it a minimum of 5 days a week. Even if it's just walking a 2 miles around your neighborhood after dinner, it's something if you're currently doing nothing.
What seems to work best food wise is whole foods, that you cook yourself. If it comes in a box or frozen package, it probably isn't a very good choice. Learn to read labels REALLY well, and figure out things like net carbs, sodium levels, etc., and check out both here and bariatric recipe sites like http://theworldaccordingtoeggface.blogspot.com/
Proteins should be the main part of each meal and every snack: things like fish, chicken, lean cuts of beef, cheese, yogurt, even Beans and lentils. Healthy vegetables - leafy greens, red peppers, squash, zucchini, avocados, broccoli, cauliflower... watch the ones that are high carb like corn and green peas as even healthy veggies can have high carbs sometimes and you need to be aware when you eat them. Should also be including healthy fats like coconut or olive oils and things like nuts or avocados have fat too, but it's a good fat (just watch the amounts and calories). Watch things like lunchmeat that are usually high sodium (again, read labels!) and be aware of times of day that you might be weak and have healthy Snacks on hand to prevent the quick stop at the drive thru or dropping by the office vending machine.
MEASURE everything. You can't rely on eyeballing food amounts. Get a digital scale, and weigh your food so you get accurate calorie counts. It is way too easy to guess and over-estimate your food portions.
And you might need to see a counselor that deals with eating disorders if you can't get control of your eating and get your head in the right space to succeed at this. Please don't take this as being mean, but worrying over what others did and comparing your lack of success while eating bad foods isn't helpful or realistic. But here's the thing. You aren't a failure unless you give up completely. Don't give up, and you will succeed.
