I take Topamax for migraines but I do know that for a lot of people certain foods can trigger them. You should keep a food diary (really everything you eat) and then note when you get the migraines.

It might not be the amount of food you are eating but the amount of one thing your body is having a reaction. Keep track of what you are eating you may see some kind of pattern on what you are eating that could trigger the migraine. If I have too much sugar I will wake up in the middle of the night with one. I have also read lots on this subject and found that different seasons cause migraines. Keep track of your daily activities and what you are eating and even the weather and see if this helps. You may have an allergic reaction to a food and the way your body is reacting to it is by a migraine.

Good luck

I have binge/closet eating issues myself - and I know that a migraine can trigger a binge for me because I get so upset, etc.

ANYWAY - my point being that a lot of these things can be related. It can be stress triggering both. It can be the foods you eat when on a binge (like processed, over-chemicalled, etc).

As you work through both issues, you'll see relief of both. Try keeping a journal - both of food AND feelings. As well as the migraines. You will see a picture of what happens if you do this for a few weeks.

My binge eating sometimes triggers my migraines (rather than the other way around). When I have a migraine, I don't usually want to eat, just take ibuprofen and pass out in a dark room.

But in the past when I've binged on junk food containing a lot of sugar, fat, salt, preservatives, artificial colors and/or MSG, it sometimes sets off a migraine. Cutting out junk food, plus eating healthy meals on a regular schedule, seems to help me get fewer migraines. I'm not sure if it's ingredients in the junk food or the physical & emotional stress of bingeing that causes these migraines. But since I also feel less depressed, nauseated, irritable and obsessed when I don't eat these foods, it's worth it.

(Junk food = cookies, cake, ice cream, candy, pastries, chips, pretzels, French fries, sugary granola bars and breakfast cereals.)

Oh, yeah, eating those foods will make your blood sugar soar, and then on the drop trigger a migraine. At least, that's how that would go for me. I've struggled with overeating compulsively as well, and I tend to use binging as a form of pain and stress reliever. You would definitely be better off putting some more proteins in your routine, like nuts or eggs or whatever. That would help control your blood sugar more and maybe help with the headaches.
