All posters have a good advice. I do not think flushing every week is a good idea. Liver-Flush every two weeks is tolerable. I am sure despite your good diet there seems to be some depletion of vitamins and minerals that are not being replenished. Anger is the first sign of depression.
Take a break and feed your body with live raw foods. Also we need good fats from nuts, seeds, avocados, etc. It will calm you down. And meditate.
I personally am not a fan of Coke, it has too many junk stuff in it.
