I'm sure some of that 7 lb. weight gain is water weight. Most of that should come off fairly quick! Stick around and post in the Motivation and Support forum. I've personally found that posting with others who are also trying to shed pounds to be very helpful! All the best to you!
If you're tired of starting over, stop giving up!
