I know that when I’m sleep deprived, trying to do a heavy amount of thinking or engaging in stressful activities can make me feel more pained than it would otherwise. Even if your headaches aren’t related to that, it might be a good idea to try to narrow down more precisely how much of the night you’re usually asleep/dreaming in case you are suffering sleep deprivation. However, from your description, The evidence of you being/not being sleep deprived is mixed.
Evidence which indicates you’re probably NOT sleep deprived:
You spend 10 hours between going to bed and waking up.
You enjoy lounging in bed and rise slowly as opposed to being forced awake.
Evidence which would seem to indicate you probably ARE sleep deprived:
You don’t have a fixed bedtime.
You wake up multiple times in the night, and in some cases have time to think a substantial amount before going back to sleep.
Also, I don’t think I would normally get sleep deprivation headaches in the middle of the night if I was still in bed.
I would say this is probably not the cause of your headaches, but that it might be worth trying to look into your sleep cycle if nothing else pans out.
