I myself have a 3 year-old son diagnosed with pku. at first I was so disappointed and so exusted. after that I found very nervous problems such as hair loss, thyroid, skinny face. sometimes ago I read one book by Brayan Tracy that he said if you think about misery, you'll certainly attract them. this is a fact that I myself experienced with all my soul, until I think about my baby's disease, I attract so many problems about my own and my son's health, but now I like just think about my happiness and successes. I hope one day someone find sth that causes phe to come down after eating protein foods.
