My doctor said if you eat until you feel restriction, you are stretching your pouch and making your band useless. He said to measure your portions (1/2 cup Protein, 1/4 cup veggies, 1/4 cup carb) and eat that and only that. Then 30 minutes later, drink a quart of Water. I had my surgery January 10th, and lost almost 50 pounds with an empty band. My doctor said as long as I am losing there is no need for a fill. He does fills only if the patient has gained or hasn't lost anything for a couple of months.
Also, keep in mind that this is a slow process. You're not supposed to be at your goal weight immediately. My doctor said losing more than 2 pounds per week is dangerous and unhealthy.
