Hi! I have the same issue with headaches. I am about 4 1/2 months out from my SAH. The head discomfort limits my ability to "sleep in" when I get the chance. I can deal during the day, but really bright lights, flickering images on TV, etc. really make me things worse. At night, the veil drops and the dull aches sets in. Over time, though, the pain is less, and feels much more dull. I get the occasional throb through an eye into my brain stem area, but it does become much more manageable.
I hope this helps a bit. It is hard to be patient, but you seem to be doing very well!
Best,
Noah
