is Dr.Lam's information reliable? Don't know where to start!

Trying to battle adrenal fatigue still after not making any progress with my local natriopath and am looking for a good beginners protocol in trying to deal with this as all the different avenues in recovery and supplements to try seem rather endless. The wired and tired aspect of this posted on dr.lams website definitly rang too for however I can't afford any sort of personal consulations with him and am unsure of the validity of his different programs?  I wanted to try taking some L-thenaine but I read on his website that supplementing amino acids by themselves can potentialy do more harm then good. Really don't know what supplements I should begin experimenting with as I don't want to make myself worse. Only thing that's helped me so far is clean eating and regular exercise.
