Wow, little update.

I started taking a micro-dose of vitamin b6. 50 mgs give me noticeable tingles (which is a well-known issue with b6). However, taking a far smaller dose around 5-10 mgs really, really helps with this headache. In fact, it's largely gone after just one day of b6.

Could be placebo, but I've tried many other supps before, even more hopefully, but they haven't worked at all.

This is really interesting...
