That's a great video, Thank you.
She says all sleep problems, including apnea, are caused by having Vit. D3 outside the correct range, which should be 80-100. If your Vit D, by D-hydrox 25 (not 125), is outside that range you will have sleep problems of a wide variety of types. She also says that paralysis, including choking or unable to breathe always happens to everyone in a particular phase of sleep. It seems to be required for healing the body. (Of course it shouldn't be happening when you are awaking.)
She says to take large doses of Vit. D3 to achieve, and then to maintain, your Vit. D within those levels. As to how large, possibly up to 10,000 iu daily but to be very very careful on the dosage and to have your Vit. D checked every two months until you can maintain it steadily. She also says never to take Vit. D2.
She says a C-Pap machine will help while you are adjusting your Vit. D levels.
I suspect that as she learns more she will determine a seperate range in Summer from Winter.
IMO try sleeping on your side. Also, try sleeping on a futon on the floor.
