Dr. L Wilson? I'm sorry, I have not heard about this doc. The only Dr. Wilson I know is Dr. James L. Wilson, the person who named the syndrome "adrenal fatigue" in the nineties and who has spent most of his life studying stress and the adrenals. His presentations in Australia and NZ have changed the way practitioners view and treat AF. It is unfortunate that there are many self-proclaimed "experts" out there when it comes to AF. I'm still a student of Dr. Wilson when it comes to AF, even though I have treated patients for twenty five yrs.
Once a doc fully understands the significance of treating stress, their practice will change as they begin to realize that most all patients they see present with the manifestations of stress to some degree. Some have minor stress-related issues like insomnia, headaches, constipation, etc. Whereas others have more serious afflictions right up to burn-out of severe AF. I wish more docs studied AF seriously, stress is possibly the biggest cause of disease and human suffering, and big pharma just make $$ out of peddling their toxic wares to treat all of the many manifestations.
