Another piece of advice I received this week is to think about yourself in terms of who you want to become. When you're faced with a choice, think to yourself "what would future me do?" and apparently this helps you make positive life changes.
So far this week it's helped me not buy chocolate cupcakes on two occasions. I think the reason it works is because the future you is still you, so if future you can make certain choices, you can too.
I've only used it as a technique for avoiding binges for two days, but it's fairly successful, so give it a try!
