Frustrated - Stall for 3 weeks now

OK...Just a short rant and I will leave it alone.

3 weeks now and the scale is up/down/up/down. I have not lost anything in about 3 weeks.

I think I am losing inches but Geez!!!!!
Keeping track on myfitnesspal.com
began walking on treadmill last week.
Tried the elliptical but my knee started bothering me so went back to treadmill until a bit more weight comes off so the knee doesn't hurt so bad.

Bought a FitBit and started wearing it today. (been awake 4 hrs and over 2000 steps so far)

Just a frustrated rant.

You will find out that this sleeve of ours has a mind of its own.  I am ten months out and I have had weeks at a time where I did not lose a single pounds and then the next week lost five. The best thing you can do is stick to your doctor's plan  and trust in your sleeve.  It will surpise you every day!

I agree with Felicity, just continue to follow plan and do what exercises you can, and you WILL continue to lose!
Hang in there, lower numbers are coming your way! :)
