Hi bucci,
I'm so sorry to hear this about your Dad.. I suffered from lyme rage and had no idea what was causing it until I called the Hansa Center (even though I never went there) but back then I was following Dr. J's protocol from his first book.
I cursed people out, said horrible things to my family and friends, said things I didn't even remember saying until people told me what I said and I was horrified with myself..
I remember becoming really scared and feeling so lost inside because I didn't know at that time what was causing these rages...
What helped me was after I called the Hansa Center (it had a different name back then), a staff member suggested a supplement to me that would bind up and rid the ammonia out of my brain and body (today it is called the Neuro-Antitox Formulas).
I remember taking a product called Silphitrin and after a month or so I felt calmer and the rages were happening less often so I continued on this product as well as another one called Pale Spike Lobelia (I don't think Dr. J. uses that botanical anymore)..
I don't know if this will help your Dad but it helped me tremendously. To this day I don't believe I ever had bartonella but who knows? The important thing is I am symptom free and stayed that way, knock on wood...
Maybe reading this article would help:

This is really a great product to help with the neuro problems:

Let us know if things get any better for your Dad.. I guess it was a good thing that I lived alone when I was sick.. If I was married I am sure I would have destroyed that with my rages..
Hang in there,
Denise
