I can understand. I was banded 12-14 and lost preop and 1 week post op. Nothing week 2 and week 3 I'm the same despite low calorie intake and exercise.
I have two thoughts, quite possibly we are gaining muscle from exercising.
And if you have no restriction, the tool is there but not yet ready for use. Meaning you have a band but until you get a fill it's not really doing much after your swelling went down from surgery.
Hang in there. I am confident it will happen.
