I'll join the challenge for the month. I have only been back to CAD/CALP since this past Monday, but I am firmly on plan and want to stay that way.

Challenge for Nov on my CALP plan is

Make sure that I balance my RM
Eat enough at CM's so I don't overeat at RM
Drink all my water
Try to exercise at least 3-4 times a week.
Make sure I keep posting to the forum even if I start to slip.
Since it is Nov and Thanksgiving is this month, I want to make sure that I stay on plan during the holiday.

Having this challenge is an excellent idea. Come on everyone. Lets here your challenges for the month..
