Let's try this. What are you eating? If you are eating lean protein and veggies, then the amount really shouldn't matter.
I haven't thrown up, dumped, or found a food I couldn't eat at almost 4 years out. This surgery isn't supposed to be a diversion from food, but a reset for food and your life. Eat nutritious, non processed food 90% of the time, drink lots of water, and move more, and you'll do just fine. If you are really concerned about how much you can eat, weigh and measure your food so you won't overeat.
The tool itself is really only temporary in the grand scheme of things. Over time it becomes less effective, then it's all on us. Practice good eating habits now and take advantage of the honeymoon period while you can.
