Sounds like you are killing off more than your body can deal with at one time. Should be drinking 8 ounces of preferably distilled ozonated water before and after pulsing. You might want to stop except for the ozonated water and let the body detox until you are back to normal. Then ramp up slower next time.
When I first used the Beck Protocol I thought everything was ok until I developed flu like symptoms a week or so into the treatment. I quit and waited until I was back to normal and started again.
For a typical treatment you eventually want to work up to 8 ounces of Colloidal Silver per day, 2 hours of blood cleansing and use the magnetic pulser if needed. No drugs or anything else that is toxic. After you ramp up continue for at least 30 days. Take a break and repeat if needed in a month or so.
