I won't disagree that NB via Dr. Wilson can take some time, but it can be a totally life-changing program. At least that's been true for me. We are all impatient to get well, especially if we've been unhealthy for a while. But I am so thankful to have found NB and to be tackling the "roots" of poor health. There are lots of things we each could do to feel better fast, but there is danger in their making us worse in the long run.
You are on the right track when you plan to keep researching. And while I agree that Dr. Wilson doesn't know everything, I believe he is quite thorough in his research. He is constantly updating information on his website. He's really dedicated his life to NB and has an excellent track record of guiding people to robust health. The practitioner I work with has been his life-long close friend, and I have learned a lot from both men.
