I just joined this group called the Art of Living and had a few very inspirational moments that I wanted to share in my post. The very basic learning is to get rid of all things extraneous in your life - stuff you have accumulated - both materialistic and emotional - over the years. It is amazing when you sit down and make a list, you will realize how long it is.
I personally took upon myself to de-clutter my life and it is amazing how de-stressed I feel. In fact it has helped my create more time for myself and manage my diet better. PKU or not, I would highly recommend you try the Art of Living to see if it helps.
