Demi - have you tried to keep a daily diary of what you did, like where you went that day, what you ate, even if just chewing a stick of gum (how many pieces, what time, how long chewed, brand of gum) for a time period to see if you can help to figure out what causes it to be cyclic?

This is how I overcame the need for migraine medication. I figured out most of the triggers and then avoided them.

I have days when my "brain fog" is much worse than others and I have considered doing this again to see if I can figured out something that makes it worse and then the steps to prevent that.

As to the rage, any allergies. I know rage is not listed as something that happens when you are allergic, but I lived in a house that had mold in the duct work due to the CAC malfunctioning. We don't know how long it was like that. I was out of the house for several months, calmest I'd been and the happiest I'd been in a long time. Went back there to start cleaning it up and getting it read to rent and within an hour, I was ready to strangle my husband over something very petty. Stepped outside, got some fresh air and started thinking about it. That was exactly how my emotions were for I don't know how long while I lived in that house, it has to be something in the house. Went back in and started investigating and I found the mold. Fortunately for us, it's not the black mold that can ruin a house and it was contained to the duct work. I'm not saying that I no longer have any emotional difficulties, just saying, this rage what would pop up out of nowhere and over the dumbest stuff (didn't think so at the time) is gone, I still get upset, but I have control now.
