You have only had one fill and sometimes it can take a lot more before you get the sign to stop eating. I know someone personally who had his band completely unfilled because he was going on a cruise and he wanted to binge eat on everything. After the cruise he decided not to get re-filled because he liked his food too much. What was his point in getting the band if food was more important than a weight loss? What's my point in saying this? You probably will need a couple more fills before you feel like there is a stop point. With binge eating there is no stop point. You had this surgery for a reason, it is not a lose weight fast scheme. It takes time for the body to adjust. My friend who had his band unfilled has gained all his weight back plus more! Do you really want that?
If you stick with it and choose healthy eating the binge eating will take a back burner to healthy eating habits. There are times when I feel like I could eat the whole world. I choose not to. I didn't have major surgery just to see it all come back.
If you feel you must talk to a psychologist and by all means let your bariatric surgeon know.
By the way, you can still go on a cruise and lose weight. I've done it and lost 10 lbs on a cruise. I did not deprive myself of anything. I just ate smaller portions.
I know you can do this. It just takes time, perseverance and a lot of determination. Good luck and I know you can do this!
