Hard to beleive this is the whole picture. My son lives with low seratonin-- carbs drive up his seratonin levels. Cant tell you the mechanism, but I know it works.

When he is especially cranky and "off" this is another time that he needs to EAT. Again Im not clear on the mechanism. Is he hyperglecemic in this case??? After he eats, he is a totally different person.

Dr Amen addresses the low seratonin and suggested a complex carb like sweet potato.

Dr Amen is the only doctor that understands this phenomenon, as bringing this up with my son's doctors, I get "blank" reactions, poo-poo'd or otherwise shut down.
