Thanks, haidut. I wondered a little bit about a reaction to extra dopamine but didn't realize headaches could be such a big deal side effect. The day of the killer headache (and nausea) I was incorporating another dopamine boosting strategy. Yow, it was something. I thought maybe it was antiviral activity (which I don't really know much about, @TubZy) but the "too much dopamine" hypothesis fits really well for me.
So maybe I don't need any extra dopamine. LOL
Lol, fair enough
