Roo, I registered just so that I could respond, because I am in the EXACT same position.
I was also sleeved on 10/21. I lost 13lbs in the first two weeks and only one since then. You are not alone!
It IS really discouraging. But I just keep telling myself that the scale WILL move eventually. Are you taking measurements? Mine are going down and that has been helping a bit. Its not all about the scale...
