Do you have an enema bucket setup? The things you've done so far are excellent for removing toxins, but a deep enema would really help you feel better fast. If you don't have one, get a couple enemas from the pharmacy and use both - it takes about 20 oz of fluid to get up to the transverse colon.
Foggy headedness and irritableness is usually due to large proteins and toxins passing through the bowels because of leaky gut, and/or the liver being so congested that it cannot remove toxins from the blood, and so they pass through the brain blood barrier.
Try drinking warm water instead of cold, with lemon juice and cayenne pepper. Add maple syrup to taste, and if you have any, apple cider vinegar. Tastes awful but will help you detox. If you have any B vitamins and MSM or liver supporting herbs, take those too. You must have really stirred things up! :) Fast or eat only very simple foods for awhile. No dairy, flour, sugar, or fruit except for green apples.
