PIP,
Something about those evening hours that inspires gorging. Maybe habit, maybe boredom, maybe hunger.
We must all deal with that urge to keep running back into the kitchen for MORE.
I find two things help: going OUT at night (legitimate theaters don't provide snacks

) and eating later (sometimes tough.) Maybe going for a long walk the iinstant the cravings begin is a good idea.
You can always having carrots, celery, oranges around. Have a cup of coffee or tea when you get the munchies.
Another thought on the "immediately after dinner" urge. Try waiting an extra half hour or an hour to allow your dinner to start digesting and raising your BG a bit. Then maybe the urge to "continue dinner" all night long won't be overwhelming.
We do what we CAN!
Signed,
Starvin' Marvin
