For me I am on my 4th fill, my first two were both .75CC, the third was 1cc and 4th was 1cc. total of 3.5CC. I have lost the most weight so far with the 3rd fill after a month I have lost 10lbs. Next week I am scheduled for either an adjustment or stay as is. I think I am happy with the progress with this last fill and may either be on the green zone or the edge. It is for sure tighter in the morning than the evening. but each person is different. hope this helps and good luck on your weight loss journey.
