Remain calm, whatever you do. Sorry to hear about this change and your anxiety. Have you done anything different in terms of food or water? TOM?
If all has remained exactly the samd, it seems your body is putting up a good fight.
Just curious about which program are you doing? Maybe you are retaining fluid for some reason.
I read something a long time ago in the Atkins book I think, and it worked for me.........I had an over population of yeast in my digestive tract due to all the meat and cheese I was eating. I started taking an acidophilus pill daily, and then the scale started to move downward again. It was like a miracle. You might want to try that. It certainly couldn't hurt you.
