Re: Question for Elmhar
Gosh, Betsy Ann, I really don't know that much about LDN.
What I do know about Teitelbaum, is that his books will often suggest dosages of alt. med stuff (which I'm more familiar with) that seem higher than the dosage that works for me. So, perhaps it is that he writes what he has found to be both "safe and effective" for many people, while some of us will find an effective lower dose.
Things that are dosed twice per day may be so dosed because of the typical half-life of the drug is less than 24 hrs. Some individuals have atypical metab. & the drug may stay in their system longer, or shorter, than the average person.
It's also possible there is an error in the book.
If once a day works great for you, I wouldn't fuss with it too much. I suppose you could try a divided dose, to see if there's any tweaking that could be done, but you the saying, if it ain't broke ...
