Lottie, you really have done amazingly well and I wonder whether the fact that you're so much closer to your goal now means that there isn't as big and obvious a need to get right into it, if you know what I mean! But think about back at the beginning, when you started, I don't think when you pictured being at goal it was to be how you are now, you're so close, you just need to stop faffing about and get on with it again!! It's always hard coming back after a couple of weeks off.
You're paying what, £36 a week to do this diet? That's a lot to be paying to pick and eat things which jeopardise your losses. So next time you feel like picking at something, imagine a £36 price tag, imagine that to eat that, you had to hand over £36 of your hard earned cash, I think you'll soon see that it's just not worth it!!
What have you got coming up that you can use as motivation? A birthday? Holiday? Keep thinking of that thing you've got coming up that you want to look even more fab for, think about how picking is slowing that down.
If you use a calendar, you could get some of those sticky stars and on 100% days put a gold star, on naughty days put a different colour star, that might help motivate you if you'd want to see lots of gold stars!
But my biggest tip of all is just to forget about it, don't worry and stress about yesterday just draw a line under it because today has enough hurdles of it's own, tomorrow will get here in it's own time regardless of how much you worry about that, so forget about that for today too. Just take everything one day at a time, focussing on the here and now. You can do it missy!!
