I have successfully overcome my BED symptoms, but I still eat late at night (11pm to 1:00am-ish). I go to bed around 3:00am. I was a late night binge eater in order to hide the overeating from my family. Now I no longer binge, but the late night eating stuck with me.
Like any habit, you need a system to break it. Think of yourself as a smoker, or an alcoholic. What would you do to stop feeding the habit? You'd stop buying cigs and booze, first. You'd work on setting a schedule, with alarms, if needed. Fo' sure you'd set an earlier bedtime.
And confess. Tell your family. Agree not to eat EVER outside their presence.
Get more proactive with measuring tools--a scale, spoons, cups--weigh and measure everything.
Substitute. If you feel a compulsion to eat, jog in place for five minutes. Buy smaller clothes at a thrift shop so overeating is uncomfortable. Start a handsy habit, like embroidery, macrame, knitting. Get a recovery partner who agrees to be on call 24/7. Call eachother all the time. Stop isolating. Take selfies every day. Get a makeover and practice different looks. Visit a salon weekly to change hair color or have a facial. Spend food money on an evening gown. Go big or go hide in a closet crying!
NEVER say "It's hard." That is an affirmation. Say, "It's easy." Your surface awareness will disagree, but there's a core part of your consciousness dying to hear it.
Create your system, but keep it simple--3 or 4 things you'll embrace when you're in crisis. Adding too many is sabotage. Thing Number One MUST BE "No eating after dinner, EVER."
FYI, I'm also nocturnal, though I regret it every day. It goes back to childhood. But if you drink more water and get more sleep, things that sag will spring back, and creases will fill, wrinkles will plump to normal. You'll also feel smarter, remember better and attract more people to you.
If you don't believe that consider this: you may be putting up walls, unconsciously or deliberately.
I used to say, "I'm 60" or whatever, with pride, expecting to hear, "Wow, you look like you're in your 30s," etc. Well, there came a day when no one said that anymore. How did they know? My wrinkles and creases announced it.
Drink water, get sleep, have moisturizing facials.
