I hear you...
I was banded 9/27/07, and my losses have been negligible. I lost 18 lbs pre-surgery, and then floundered. Last year at this time, at 262, I started doing Atkins and managed to get to about 240 on a roller coaster ride.
I have presently been doing Medifast for the past month, started on 2/1, and I have barely seen a 5 lb loss. I'm so frustrated, I'm doing everything on plan, never going over 900 calories a day... and yet I am struggling with every pound.
Glad to hear I'm not the only one...
