When I use Scalar or even frequency in general through sound etc. My head and body twitch or shake. Is that normal or am I really sensitive? I did have a few anxiety attacks and that was scary. Is that herx or?

Drink plenty of pure water. Ideally, you should drink six to eight pints a day, half of it before noon. The water flushes toxins and dead organisms out of your body more quickly, and it improves your electrical conductivity.
If you feel nauseous, faint, dizzy, or have flu-like symptoms or headaches after exposures to the scalar field, please drink lots of pure water or lemon water and shorten your future Spooky2 Scalar session times appropriately.
