Aww Sandra I know how you feel, It is so easy to slip up & so hard to stay on track.
I've been picking & bingeing over the last couple of weeks.
Last week was a particularly bad week, where I had a birthday meal out, christening & a training day with lots of food, but even after eating that one meal each time I couldn't stop myself picking until after my weigh in.
I put on 3lbs!!! so this week I have stuck to the straight & narrow, I've found the first part of the week easy, but now its Friday I'm a little worried. Its that Friday night - treat yourself problem.
I wonder if maybe some of us just need a break at some point, I know I felt like I needed one, but my holiday is next week & that is what has kept me going this week, otherwise I don't know where I'd be now.
Have you spoken to your counsellor?
Have you tried going back to the green book?
Have you set any mini goals & treats?
Keep posting because that can only help.
