If the author is reading this, might want to consider the possibility of an onset of chronic "silent migraines" which can have quite the nauseating effect but without the headache. I suffer from them and they are debilitating. While reading your article, I kept thinking it would eventually get to the part where you discovered you are having migraines (which also tend to run in cycles of a couple weeks to a month for many people, myself included), but no mention of this anywhere, so thought I'd point it out.
