What are your calorie goals?

I was banded in Mexico, with directions from their nutritionist. I also have a local nutritionist, but neither one has given me a calorie goal included in my plan during recovery. I have a telephone appointment coming up in a few days, and I will clarify, but I'm really curious to know what the rest of you are doing and what is/isn't working. In normal dieting, I know a low calorie diet can sometimes make the body go into famine mode and lower metabolism, but does that happen with the band? I would like to make my goal 900 calories/day - has anyone been successful with that kind of number?
