[Tarsul]

When I developed pre-diabetes symptoms (having to drink a lot - like 5-6l per day, consequently having to pee a lot, when not doing the first: getting headaches), I noticed that cutting on sugar meant (next to other benefits) that the thirst-induced headaches were the first thing that went away. Not the thirst itself (still have it).

However, not an expert on headaches and can't say if it has anything to do with the migraines in the article. But the point that reducing sugar helps in a myriad of ways, stands and is worth repeating.
