For me, it was extreme stress for a period of three yeras, and my adrenals were [self diagnosed only] stressed as well.
I corrected the thyroid first, and then the sleep thing happened by accident and through simply connecting the dots. But it has been one of the greatest benefits.
To this day, I sleep every night, and through the night, the kind of sleep that is even tasteful, like I can chew on it.
However, I had been drinking lots of water, lemon, and celtic Sea Salt as well as taking the B12 sub-lingual prior. So maybe it was the combination?
Also, the source of tremendous stress, was gone at that time - so that must have all converged to work together.
Well, I'll check on you again soon - Maddie
PS: also note that sometimes, I choose to try things based on intuition, the same way I purchase my greens. My body is very outspoken, so what works for me may not necesarily make sense for someone else.
"oral megadoses of methylcobalamin Ė the most bioactive form of B12 Ė has shown promise as a regulator of disturbed sleep-wake rhythms. Methylcobalamin has been particularly well-studied in Japan as a treatment for delayed sleep phase syndrome; that is, not being able to fall asleep until very late at night and needing to sleep in every morning. Because sleep-wake disturbances are part and parcel of most mood disorders, B12's apparent sleep-wake regulatory effect could help account for its mood-stabilizing benefits. In a 1996 study by G. Mayer et al., three grams a day of methylcobalamin, but not cyanocobalamin (the form of B12 in most supplements), managed to decrease sleep time yet improve sleep quality and daytime alertness in a small group of healthy men and women.
