Wow. Reading some of these makes me wonder. I never realised when I made the decision to come off of the diet I would suffer with panic attacks and agoraphobia. 6 years down the road and it really sucks. Had I realised it was connected to PKU I would have gone back on the diet sooner, I hope it is not too late. When I came off the diet I put on a LOT of weight. I think going back on the diet will help me be more healthy in general. As for the psychological issues, jury is still out on those.
