First off, congrats on your weight loss this far.
I can only speak from Personal experience with my journey. My success, I feel can be attributed to logging everything and I mean EVERYTHING I put in my mouth. Not only does it log calories, but proteins, carbs, etc. I try to eat my carbs in the morning only and rarely after 6 at night.
I also change up my exercise each day with cardio everyday, lower body and upper body alternating days. My cardio is either running, swimming, squash but never the same two days in a row. I feel it fools my body into burning more.
It's worked for me.
Just don't give up. You've come so far and sacrificed a lot by being banded.
Good luck!
