Insomnia causing binge eating?

I am a 62 year old woman and never had trouble falling asleep. NO new meds nor life style changes and long past menopause. When I can't fall asleep I have been going on incredible eating binges. even though I am not hungry nor do I have a food craving at this time and I don't want to eat but I can't stop. I know this is weird but it is almost like I am being forced to eat. This happens when I have trouble falling asleep.
