I was born with PKU but moderate PKU. On january 2, 2009 I felt weird at the gym when I was working out. Finally I got into the doctor and they said my levels were 1745. I have always eaten everything I wanted. I’d eat 1 pound of sausage which I made myself. Now I eat 20 grams of protein and my head is still not right. I think you could say I now have classical PKU. I didn’t before. Has anyone else had something similar to this happen. I have never had any problem until this year.
