The hammer-hitting herx reactions were definetly pre-doctrine. That's the beauty of the doctrine running--it's addressing all that's involved. Much of what Hulda Clark says goes together in her book, has been proven to be right time and again when it's been checked with the biofeedback testing. For example..when EBV is found, always check for the Pancreatic Fluke. When CMV is found, always check for the Dog Heart Worm. When Coxsackie virus is found, always check for ascaris, etc etc.
When parasites are killed, there will always be toxins/metals involved. When Buski's are killed..pre-doctrine, you could expect to feel like it was a huge sledge hammer that had hit you..and that's when you'd also know not to talk to Newport because he was grumpy when he was going through a Lead dump :)
The doctrine, has taken a heck of a lot of work and time out of dealing with this stuff, and is a gazillion times more effective than what we were doing pre-doctrine.
BTW..this is no short term thing, which can cause impatience and frustration with people, because they don't think it's happening fast enough. It's back to that safety factor.
Practice dowsing so you can be able to check for your own progress, and you can check on what the doctrine is working on for you. Doubt and fear, are not from your Guides. Learning to trust that they really are watching out for you, is a big step for alot of people in the beginning.
