I had my surgery almost a year ago, so I can share a little about what you are going through. There is a normal stall around 3 to 5 weeks out from surgery. It will last about 2 weeks. You have to remember, this is around the time when you are adding regular food for the first time. Your body is trying to adjust. You are in monitored starvation, you'll start losing again.
To give a little of my background, I was 261.5 on July 24th, 2012, when I had the sleeve. In three weeks I had gone down 22 pounds and went from a size 24 to a size 18. The weight continued to go down an average of 11 lbs a month. I am now 80 lbs down without much exercising. (I am gone almost 13 hours a day with my job and have little time at home). My doctor told me when I hit 180 I would hit a wall. He was correct, but I think it is more that I was grazing a little and therefore, eating more. I have backed off of doing that and am losing again. I did not gain any weight while doing this, but did not lose either. My goal is 150, so I have 30 lbs left to lose. Most think I have lost enough, but I am 5'9" and 150 is not an unreasonable goal for me and I see the poochy abdomen and flabby tops of my thighs that could use a little weight loss.
I am now down to a regular (not women's) 14 and love shopping for clothes (to my husband's dismay). This past year has been like winning the lottery. It has been a wonderful journey and I would do this again in a heartbeat. Don't despair about the stalls, they are a part of the process - learn the process and you will do well. Determine that you will NEVER go back to the way you were. Enjoy discovering the new you!
