I use to have that exact problem. I saw so many naturopaths, etc. For me, taking the "B" vitamins, along with a good multi-mineral, helped. However, I still was more prone to the anxiety in the morning and by night, I felt comparatively good. I think it has something to do with our adrenal glands. When you first wake up, your body is in full-gear, ready for work, etc, then, as the day goes on, and you move around and release some energy, the adrenalin subsides some.
