Wheatgrass, wheatgrass, wheatgrass... :) Jokes aside it sounds to me that you have all the makings of an already thorough regime.

At a fundamental level, all things are energy and the only other contribution I would like to suggest is blessing all that you take into your body. I strongly feel that blessing with love and gratitude in conscious recognition of where our food and drink comes from is the last word in detoxing, as we energetically align it with our bodies.
What follows is my personal blessing and you are welcome to use it, modify it or (preferably) create your own heart-felt blessing:

Bless this food (water, etc) with love and gratitude to my body
As it cleanses, refreshes and purifies me.

Bless this food with love and gratitude to my body,
As it heals me with the natural and loving energy of my Mother, Earth
As it nourishes me with the natural and liquid energy of our Father the Sun,
of the Air and of its Self
For the great good and higher love of all Souls in the Universe.

If you look up a recent post of Chris' he goes on to discuss his regime in quite some detail, graphically! ;)

With love,
Kelvin
