I work with Pam Killeen and really like her. She has a lot of experience. She is pretty responsive.
She maintains a Facebook book group, which is very helpful. It allows us to all learn from each other, and when she answers one person ... we all benefit.
One of the curezone member "hopeformyadrenals" used to have a really hard time taking supplements. She used the "biotuner" for a couple of months and then found she was able to handle the supplements.
One nice thing about NB is that there is generally no herbs.
