I'd also add that calculators won't tell you the whole story. You should listen to your body. If you feel that you need more for a night time snack, you should plan for it. Make sure you leave X amount of calories for after dinner and it will no longer be a binge.
Another thing is, as you get more into calorie counting, you'll find low cal options of your favorite things so you'll be able to eat more! That was the most fun for me, I took whatever I was eating and found an alternative (ex: my wraps used to contain anywhere from 120 to 240 calories in each wrap, simply because I was ignorant about calories. Now all the wraps I eat have about 60-80 cals each
)
Good luck! Calorie counting gives you amazing control!
