You are having a Herxheimer response to the silver killing off the bugs. Cut down by 1/2 the amount of silver you are taking for 2 days and then go back to normal. Also drink plenty of water and if you can make it or buy drink some Ionized Water to help flush out the body- just drink plenty of filtered water to get rid of the junk the silver is helping to kill. I make my own Ionized Water (ozone) to drink when I get sick
