Those migraineurs who experience "weekend" headaches or headaches precipitated by oversleeping should try to awaken at the same time on weekends as they do during the week and to maintain a regular sleep pattern throughout the entire week. Moreover, it is essential for the migraine sufferer to get enough sleep, as fatigue can provoke a headache. In fact, fatigue is one of the most common triggers of migraine headaches.
A sudden stopping of the use of caffeine can lead to abrupt vasodilation and a "caffeine withdrawal" headache. Caffeine is also a stimulant, which can add a letdown feeling after the effect wears off. This kind of headache is common in heavy coffee drinkers. One of the factors contributing to "weekend" or "holiday" headaches may be caffeine withdrawal. If a person normally consumes large amounts of caffeine-containing substances during the week, a withdrawal or rebound headache may occur on weekends or holidays if similar amounts are not consumed. The pain producing mechanism of the headache is probably due to the vasodilation of cranial arteries. The headache may be a persistent, generalized one that lasts for weeks. A gradual withdrawal from caffeine containing substances can help to reduce the severity of the withdrawal headache.
