I personally felt less wired first. The anxiety was one of the first symptoms to go for me. And hardly ever comes back now.
And even with all the other stuff that's cropped up recently I still sleep through the night and for the most part feel awake and tired at the right times.
I have heard other people say that Dr Lam is great at solving that issue first and foremost.
And despite those who don't stay on his program or have continued success, some have done really well.
I think it was really beneficial for me to have thier guidance, especially in the beginning. Just listen to your body and intuition, everyone reacts differently to different things.
