to 3FCs, especially to the Weight Watcher Forum. One good thing about WWs is that they have a plan for everyone. As far as your overnight gain, that's probably just a temporary water gain, and I think you'll find it gone as quickly as it came once you flush it out.
You'll find many new friends here, and tons of encouragement. These boards are full of helpful members that will be glad to help ease you down the weight loss path.
