Stage_Dolls and Wizeapple! I agree that maintenance is the hardest part. I've recently come to the conclusion after reading the NY Times article "Fat Trap" (Google) that if I am serious about losing weight and keeping it off, I'm going to have to stay on my diet forever. Luckily, I like my diet plan. It's healthy and has a cheat day each and every week!
I think I can live with that!
Whichever plan you use, I wish you the best! This is a great place to be so take a look around and jump right in!
