I was banded at Hahnemann Hospital; Dr Castellanos is awesome. Given your weight loss, he'll given you what he thinks is best (not to overfill), but he'll state to see him in a month...sooner if you feel that you're eating too much. For example, if I had a fill Jan 10th, I would make my next appt for Feb 10th, and if I felt that I was still eating more than 4 oz a sitting, I would reshedule for Jan 30th.
Because, I was lossing extremely fast up front, he was very conservative with my fiils, but now that my honeymoon is over, I'm a llittle more aggressive with seeing him for fills.
