Hangover headaches are largely due to the shock of detoxing on your brain the next day. The best cure is to avoid sudden withdrawal by either slowly ramping down your consumption the night before, or at least drinking the same beer in the morning that you drank the night before.
And no, I don't mean the one you left open half finished from the night before. A fresh one will not do any harm.
BTW - All of this professional sessioning advice also requires a reminder not to drive in the morning after a big night. Too many people don't realize they are still intoxicated.
Brands are for cattle.
Fans are cash cows.
The herd will consume until consumed.
