Yeah I can see where that would make sense. And it could possibly make sense of when I've had daytime vomiting. It does generally begin with a queasiness that I just can't shake or put my finger on. So maybe some of that is vision related. HOWEVER. lol there's always a "but" isn't there? It seems like if I closed my eyes, like when I go to bed, that the queasiness would go away... And at least a couple times now I have vomited repeatedly through the night. I just don't know...
