Why do coffee drinkers feel more clear headed after consuming caffeine? Why do some get a headache without it? Does caffeine cause any permanent brain changes and can the brain go back to ‘normal’ after years of caffeine use?

Headache is withdrawal. As a three cup a day drinker it only lasts for about a day if you stop having coffee entirely. Only other lingering effect is just maybe craving the taste / smell.
