Hi there,
I am a returner having lost 2 stone a couple of years ago, and know the diet works. You have to believe in it, and enjoy the process. It can be tough, but before, I found that celebrating the sucesses instead of dwelling on the difficulties made things much easier.
Try to have small goals instead of one big one, and you will soon be amazed at how soon the weight is falling off and I will hopefully be alongside you
