Oh, boy. The million dollar question. I've been going through this same dilemma for months now. At times I get the feeling that I need to increase herbs to subdue the symptoms, but I'm so afraid of making the herx or flare worse, that I chicken out. There have been times when backing off on the doses has helped, but the longer I treat, the less that seems to work. That's one reason why I feel like I probably need to take higher doses, even if I pulse the higher doses to get the symptoms under submission. I get psych and head stuff, too, and bouts of rage. When the brain inflammation gets worse, mold and chemical sensitivities get worse, rage kicks in along with bouts of despair and wanting to die, so of course I walk softly and am not too keen on taking risks for that reason.
I don't get the dementia type confusion or nausea, though. That sounds awful. I take anti inflammatory supplements and epsom salt baths. Kudzu root seems to help the brain burning and brain inflammation for me, but it's a dance.
