To B2 or not to B2?

Twenty eight 14mg B2 tablets
A study recently published showed that a daily dose of 400mg of B2 reduced the frequency (but not symptoms) of migraines after two months.
This morning I counted out the necessary number of little tablets and sat them on my desk. It’s a lot of pills. I don’t think I can keep this up for 2 months. In fact today I only managed 4 or 5. My head promptly revolted with an unpleasant and uncomfortable headache that’s persisted all day.
