I just started my third week too and felt irritable yesterday. It seems to be symptomatic of the toxins in the body. Parasites stir up emotional and psychological issues along with the physical. I find taking warm to hot baths at night with Epsom salt, baking soda and essential oil of lavender helps take the edge off.
Good luck. If you keep posting/emailing your progress so will I. It might help to have a partner on this journey.
