weight loss and migraine

I have been diagnosed with chronic migraine. I have suffered with it for over 4 years: I am currently 28 . I have, what feels like a million, triggers from the usual food, alcohol and stress. I occasionally suffer with aura.

One trigger which I am really struggling is blood sugar levels. Any drop in blood sugars and I have a migraine which makes me feel really sick until I have a pig out and raise my blood sugars. 3 years ago I managed to lose weight but constantly had migraine and popped aspirin until I nearly got a stomach ulcer.

Now I want to lose weight again but this time without pain. I feel I eat loads of food, 3 meals a day with tones of snacks (sometimes I eat every 2 hours!! ) but as soon as I get a calorie deficit I get migraine and have to binge to make myself feel better. I also love exercise but this can also contribute to low blood sugar despite eating an hour before exercise and drinking juice before during and after my workout. I have also decreased my intensity.

I am currently on beta blocker which are helping but have not solved this issue. Feeling so stuck with it all.

Has anyone had a similar experience and mastered it? Any advise would be appreciated.

I am also so worried about my teeth with how often I eat!!

Thank you so much for your response .
I have done bits of research and eliminated lots of foods myself such as dairy , gluten , msg to be a few examples. Since takin my beta blockers I have found I have fewer attacks when I have these types of food for treats .but my glucose levels when I am trying to lose weight are very frustrating. So far I have calorie counted what I have eaten today , all healthy wholegrain foods , I have eaten around 1800 calories and I am still feeling hungry and with a migraine . I have been hungry every 2 hours today 😕
I have been waiting to find a resource such as a book etc which had been recommended so thankeep u so much for this .
