If you find a way to avoid die off let us and the world know!
It might help to start out with diatomaceous earth as it has no side effects. Then maybe procede slowly with the other paracides. Sooner or later, mho, you are going to need to do the zapping and I know of no way, personally, to avoid die off from that. It helps to drink tons of water, take Milk Thistle & Ornithine & - per one person anyway - use activated charcoal. You need to rest all you can, get rid of Sugar & processed foods and eat as healthily as possible.
The thing is, having parasites can cause you far worse problems in the long run than getting rid of them can cause.
