My internal organs are shivering like crazy, it shows up here and there like yawns and jittery holding of my mug of tea now. Got the flush an hour after the dose, and the shivers two hours after the dose. Lots of energy, I must admit!
This makes me feel like I should take a -lot- more niacin, but it does help with a nice clearheaded feeling.
Maybe the niacin triggers internal organ shivering because of EFA deficiency? (essential fatty acids)
I asked the question at another alt health forum dealing with supplements, and the answer I got was
Glycation damage!
Probably neurological damage from so long dealing with the mercury poisoning/iodine deficiencies. The evil insomnias point towards that... It was always fish oil and fatty fish that helped me most in that situation.
