okay something's up...
What's going on is that you are losing weight in a normal way. Most people don't lose constantly. It's normal for your weight to fluctuate from time to time. That does not mean your surgeon is not effective. It just means you're normal. If that causes a lot of stress and anger, you might want to stay off the scale for a while.
Please note: I AM NOT A DOCTOR. If you want medical advice, talk to your doctor. Whatever I post, there is probably some surgeon or other health care provider somewhere that disagrees with me. If you want to know what your surgeon thinks, then ask him or her. Check out my blog.
I am 6 weeks out now, and for the last 3 weeks, I have learned to only weigh myself once (sometimes twice) a week. It will drive you nuts to see that one day you can lose, then put on a few the next morning! Your body is going through a major chance and it is also learning how to react to things differently as well! Congratulations on the weight loss!
