I don't know if anyone can say that one is better than the other.
Buhner's protocols are more popular - from what I've experienced.
You can purchase the book(s).
If your girlfriend has started to have the symptoms...you won't be preventing it...she already has it.
But, good that you are having her treat a.s.a.p.
