Take each day one at a time. When I slip and fall off the wagon I choose 2 small things to do each and eeryday. Recently it was: Get my Vitamins in...and get 3 litres of Water in. And I committed to myself that I would do it for a week. By the end of the week, that was easy. I also noticed at the end of that week that I wasn't eating as many sweets. The next week I committed to getting to the gym 4 times...check, done! and by the end of the first week the scale had moved, end of the second week, again! And then I got a slight fill...and I am pretty sure I'm in my green zone...so it's all on me now. I've my weight doesn't move, it's because I'm not working the band.
Go bag to the basics...get yourself hydrated..then walk for 30 minutes...when you feel the urge to eat, the do something else with your hands....like drink some water or paint your nails.
The bottom line is...you have to want it...no one else can want it for you. You have to find what motivates you.
Wishing you renewed motivation
