I had a stall 3 weeks after my surgery (2/10/15)...for 2-3 weeks! But I am happy to report that I stopped getting on the scale and noticed that my body started feeling smaller. Even during that non-weight loss period, I was able to get into smaller pants! AND...I lost 4lbs a week for the last 2 weeks.
Your body is catching up to your weight loss. Just stay positive and keep your head in the game!
