Sigh. A friend of mine was advised to take melatonin. He is type 2 diabetic
and melatonin has been thought to help regulate blood sugar, so I am told.
He has been having some problems, so he got blood work. The nurse calls
today and tells him he has nearly "toxic" levels of B6 in his blood.

The d#$%^n melatonin product has 500% of the daily requirement of Vitamin B6
included in the pills.

How many milligrams/day was his dose?
