Migraines???

I don't have migraines but my ex-partner did. I noticed that he got them if he didn't eat all day, and also when he had been working extra hard. They were also linked to tiredness. He said he noticed a link between them and eating cheese and also chocolate. There are lots of vitamins you can take that might help and it is also advised that you eat several smaller meals spread through the day rather than a few large ones to help migraines, but because my ex seemed to prefer to take pills (migraleve) rather than try to find a solution to the problem I don't know if this can work.
