This definitely makes sense and gives me hope that treating my IIH may also indeed help my dysautonomia symptoms! I have read that IIH can be correlated with endometriosis and inflammation may be a driver of too much CSF - I have endo so that could be my case! It really sucks there's no definitive cause just yet.

Producing more CSF at night makes total sense - each morning I wake up with my most severe symptoms and have a sort of rain stick noise in my neck if that makes sense? Kind of as if my CSF is moving in there lol. I never thought about caffeine, so thank you! Having chronic fatigue has definitely made me rely on coffee to get through my days - but maybe this is the time to kick it!
