I have suffered from migraines and headaches since childhood. I have found an electrolyte mix to be a game changer! I use LMNT or Liquid IV but I think any electrolyte mix is helpful. You can also make your own (LMNT provides their recipe for free on their website). I now drink 16 oz. of an electrolyte mix between 4-5pm and it has drastically reduced headaches in the evening and next morning. I hope this is helpful and I am sorry about the painful headaches that you experience, as well as the sleep disturbance.
