I don't know what to tell you other than I stopped doing the 7/20 a long time ago. When I Zap I wrap the handles with a wet paper towel seasoned with Sea Salt and I tuck them in my shorts before I go to bed and turn it on. That way I Zap all night. I don't know if that kills more parasites but you'll feel energized in the morning. Parazapper is a great person with lots of advice for ya.
