Other Sleep - related problems

These symptoms are suggestive of reflux related problems.

If these headaches occur soon after waking, they may be related to REM sleep, as blood vessels in the brain dilate during this phase, whereas they constrict during NREM sleep.

The more constricted they become during NREM, the more dilated they are during REM sleep. Hence if you are sleep-deprived, you are likely to have more delta sleep, so more intense NREM sleep.  Note that "Sunday-morning" headaches might be due to caffeine withdrawal (or a hangover!)

Perpetuating factors

These develop after the insomnia has set in. They include worry about lost sleep, rising late in the morning, or sleeping in the day to "catch up". This irregularity of sleep makes it difficult to fall asleep the next night, thus sustaining the sleep problem.
