Thanks, Tena, for your reply. I do appreciate your input. Surprised to read about Wilson being ill, that is not what I was led to believe by my consultant (not TV, another one). It's confusing; one does not know whom to believe.
I am sorry to read that NB did not work for you, and as you point out, there are lots of people who did do well with it. I am going to give it a fair shake, but not at the price that Faith had to pay. I do hope you find what works for you, and wish you the best of success and a full return to perfect health.
