Emily wrote everything I was about to. I think you should find a clinic (let me know if you need help with it!) and speak to them about your symptoms. The nutritionist at the clinic will be able to provide you and support you with a low-protein diet. I am very confident if you lower your PHE levels, you will begin to feel happier and more attentive. I know the feeling of both of these, and it stinks plain and simple! Best of luck…. let me know if you need help finding a clinic near you.
