Both my neuro and med sports doctor prescribed (200-1000 mg) magnesium and (200-400 mg) B2 to help with headaches. There was a clinical test that this combination helps migraine sufferers. The med sports doctor also prescribed melatonin (3 mg) for 2 weeks, and green tea 4-6 oz 2-3 times daily. Curiously, he didn't recommend omega3, but he felt curcumin was a good supplement to take for inflammation.

The melatonin didn't really help with sleep issues. But I find the headaches have decreased and its mainly brain fog and fatigue that affects my daughter now.
