Indeed a common cause of headaches is a low blood pressure and an expension of cerebral vessels. Caffeine acts against both and is therefore commonly added to drugs for these benefits. So the most likely explanation is a low blood pressure in the morning, or, of course, caffeine withdrawal.

caffeine's actually added to many tablets because it helps you digest.
In Migraine medications for example, caffeine is a key ingredient because without it the tablet would not be absorbed into your system, the migraine having stopped digestion.
could be both though
