The detox and increased tiredness? I read 2-3 weeks in a brochure I think. Here's what they say on the website:
3 to 5 days
In people who have trouble sleeping, the sleep pattern changes and sleep deepens. Many users who had had long-term sleep problems stated that after a few days of Somavedic operation their sleep nearly normalized, allowing them to wake up more rested in the morning. 3 to 6 weeks
Within 3 to 6 weeks geopathogenic stress affecting the body and all the materials under the influence of geopathogenic zones are eliminated. 1 to 3 months
Within 1 to 3 months parasitic, bacterial, fungal and viral burden (depending on diet regimen and other factors) should be eliminated. There is also an improvement in metabolism and perceivable increase in life energy. 3 to 6 months
Within 3 to 6 months the energy field of most users who did not have serious health problems should be cleared by Somavedic and if some health problems still persist, they often include only lingering symptoms on the physical level. Basically, all users experience a significantly higher level of life energy. 6 to 12 months
More serious health problems fade away and organisms of even more burdened individuals are detoxified.
They recommend drinking more water than usual to start with, to support detoxification, and to maybe put lemon juice in the water. I just drink a lot of water. It's so silky now with the Somavedic.
