What would you do?

And MY point is that at least one thing you've tried is medically pointless.

I see that you are one of those who bask in the current though probably short term success of a whole 2 years post op while forgetting what the struggle was like before your surgery.  Why did you even have the surgery?  Obviously you believe that success is all about tracking the calories and activity.  I'm shocked you didn't find that need of tool to assist to be beneath you. 

Clearly none of us believe that success is all about tracking calories and activity, because we all had surgery.  However, most of us know that tracking and activity are a very important part of the process, even with surgery.  Clearly you're missing that component.  

Ultimately, it's your body and your money, so you can do whatever you want and get that third surgery.  Or, you could get yourself back on track with diet, stick to dense proteins, and get back on a PPI to help with the hunger that's most likely from acid.  Start tracking everything you eat with something like MyFitnessPal if you aren't already.  See your surgeon and get an endoscopy to see what's going on and if there's anything actually wrong with your sleeve.  

I appreciate the way you've made assumptions about me and my beliefs! :)

No, success is not about tracking. Success is about having a tool, and using it to its maximum benefit by following post-op medical guidelines, which often involve tracking adherence to advice (protein/calories/etc.). 

I don't need my personal experience to tell me that;I'm only a single case and that's not even remotely statistically reliable. Rather, that comes from the bariatric medical literature on predictors of long-term success.

Okay, so why is it hard for you to believe that I'm following post op medical guidelines yet I'm unable to use my tool the its maximum benefit because it is larger than it should be and does not in any way do the job it was meant to do? 

1) because you aren't measuring/weighing your food, which means you have no clue how much you're actually eating.

2) because the details you posted about your diet don't actually seem compliant with a post-op lifestyle.

3) because you're getting super defensive when anyone even suggests that maybe you should revisit your own habits.

4) because you sound like a surgery-seeker who is looking for a perfect fix and more interested in blaming your sleeve for perceived inadequacies than putting in the work that it'll take to reach your goals.  

5) because there are plenty of people on the forums with "loose" sleeves who have had amazing long-term success.  

Get yourself back on track with diet, stick to dense proteins, and get back on a PPI to help with the hunger that's most likely from acid.  Start weighing/measuring/tracking everything you eat with something like MyFitnessPal.  See your surgeon and get an endoscopy to see what's going on and if there's anything actually wrong with your sleeve.  

You put very succinctly what I do not have the patience to put into words today.

"Larger than it should be" is NOT the same as "completely and utterly useless."

I truly hope you never have to experience what I have went through with this.  Maybe I did rely on my band to much for all that time, but still you have no idea what it was like to have a great tool for so long and then be left completely on your own again. 

I truly hope I never completely dismiss a sleeve that is still smaller than my original stomach :)
