I gave up on day 1 a few years ago, battled with weight watchers and lost 4.5 stone for my wedding...........didn't get to goal put lots back on.
Now I am less than my wedding weight and just think I wish I had stuck at it, I could have been a size 10 bride rather than a 14/16.
I wish I could explain to you how easier it gets after 3/4 days, it is so much better and you have energy and watch the pounds drop off.
I kept coming on the forum, puzzling, playing games ANYTHING to stop me eating, at the mo CD is just a way of life (for 50 days !!!) I never thought I could do it, but I CAN and YOU CAN DO IT TOO !!!!!!
You are not a failure, you just need the right day, right time and lots to keep you occupied.
Sending lots of luck your way and I promise, hand on heart, once your in ketosis and past that 'yucky' stage you will be so proud you have done it and will be on your way to a new you !!!!!!!!!!!!!!!!!!!!!
