RedGurl I would recommend logging your food on someplace like Fitday. I find that it makes me much more accountable.
Some of us lose slower than others.. whether its because of our metabolism, PCOS, or difficulty sticking to the band rules it happens. I have been banded since May 09 lots of people banded same time as me have lost over 100lbs that can make me feel discouraged but I keep plugging away.. lets face it w/o the band I'd probably be up not down 50lbs. I also find that I lose in fits I don't lose steadily.
Working out will help you at the very least it will help you feel better emotionally and physically. Can you walk at lunch? Low carb has also been the most effective for me and it works perfectly with the band since that food tends to keep me full up until its time for another meal. Anyhow your not failing I stayed around 30 lbs until December just evaluate and maybe make a few adjustments... the band helps you be able to make the changes but it doesn't force you...(That is said from my own experience lol)
