I have serious issues with binge eating when I'm emotional or over tired. My suggestions are: get enough sleep (good sleep routine with set bed times and wake ups) - when you are tired it is easier to overeat,
eat healthy meals for breakfast, lunch and dinner,
clear out *all* junk food from your cupboards (I keep a small container of biscuits which I limit to 2 per day and my hubby keeps his chocolate stash hidden)
eat fruit when you need a sweet snack and veggies with dip for savory snacks,
have a set allocation of snacks for the day
try counting calories for a little while to get an idea of what foods are high in calories and what are low, and how much you can eat in a day.

good luck, its hard a first but worth it

I forgot: write in a journal about what you are feeling before you eat
