I think the magic word is Graduality.
With Graduality one can become accustomed to many things. Nature works on the theory of Graduality.
The other magic phrase is: "don't miss a component". By that I mean, you should take the whole spectrum of ingredients, because they work synergisticaly. If together, they are more powerful, then on their own added together.
e.g.: B-complex has effect of 1, vit E has effect of 1. So one would say, they have an effect of 2 if together. Actually if together, they have an effect of 3. That is called synergy.
So take the whole spectrum of nutrients. All of them will influence your sleep patterns I think.
(All vitamins, minerals, oils, proteinconcentrates). Make your experiments, and be very cautious. Become knowlegable by reading about them.
The trip is gonna be an expensive one.
Don't forget to raise the dosage GRADUALLY.
I added colloidal gold recently (very, very low dosage). (Gold colloid seems to be a big gun) - Gold ions -> dangerous toxin for nerves.
I'm pretty sure it wouldn't be a big gun if I didn't consume the others (Synergy, you remember).
And don't believe me, I've never been in a university for doctors, never healed anyone.
If you don't read about them, you are lost somehow.
Once again: I'm not a medical doctor, no healer. All I say is my opinion. No responsibility.
