Hello! I am a binger. I haven't for three months but prior to that I did for nearly ten years. I understand the feeling of, "it's the weekend, time to relax and cut loose (a little)!" How do you feel about your plan overall? What are you eating and how much?
For me the urge to binge came from two things: a, overrestriction, and b, sweets. When I ate too little during the week, or even if it was just too "clean" I tended to binge on the weekend. Now I make sure to eat more fat and protein in my diet consistently.
I also had to remove sweets from my diet. I still eat carbs but not nearly as much as before and just no treats. For me they are the biggest trigger. For the past ten years my mindset was different: I'd allow a treat or two daily. I ate tons of those 100 calorie snack pack cookie things. But I find if I just don't eat them, the cravings go away. In my mind, I could have them if I really wanted, and once in a while, I will have something special. But more often then not I choose to pass on sweets. I don't know what your plan is like or what your triggers are, but this is what worked for me
good luck
