The main thing phone-wise is grey-scale and having reduced motion turned on in the settings.

Outside of that, I went to the ER one time with a persistent migraine and they gave me a bag of magnesium in an IV. They said they don’t know why but it seems to work on medicine-resistant migraines. I now take a daily zinc/magnesium/calcium supplement and it reduced them. When I start to get one, I’ll add on a magnesium dose (not going above the daily recommendation) and it helps. I also have smart lights and turning them to green reduces eye strain for me.
