5'2 and 235lbs. Hope to loose 115lbs. Realistic????

I have gone through all the hoops and rings and just had my last nutrition consultation. I am waiting for a date as we speak. I am nervous and anxious, but ready for this. I am truely hopeing to loose 115lbs. For my height and weight it is alot, and I'm afraid I won't be able to reach that goal. Is it unrealistic?

Which surgery are you planning to have? Yes, you can lose 100% of your excess weight. With the band, however, it can just take a little longer.
