Mama, I was the same as you! I was so ashamed of my weight at the start that only the pharmacist and I knew the truth! Even now I've told no-one else, not even my OH, although I do tell them my losses!
This is the best diet, if you stick to it, and that first stone will soon go, I bet by the end of the first fortnight, if not sooner!!!
You can do it - hey, if I can do it anyone can!!!!
Good luck.
