I have a couple of tips which I have found helpful. The first is holding off drinking a lot of liquids before you eat. It seems to ease the restriction and I don’t feel as full. Also, you don’t want to drink anything for about 30 minutes after you eat as it will speed up emptying your pouch.
When I wake up in the morning I have what I would consider “sweet spot” restriction. Even drinking water I can tell I am tight and it is a great feeling.
The other tip is always try to eat your protein first. My band works so much better when I work it that way. It feels like it helps block the opening and it takes longer for the food to pass. I feel full a lot longer.
