So... I'm 22 and haven't really been on my diet since I was a young teen. I guess it took me a while to realize I want to be the best I can. I never really noticed a change in myself so I didn't try. I think that is strange considering I have CLASSIC pku but I suppose I just figured everyone gets depressed, anxious, eczema-like skin, bad memory, can't pay attention. But since I have not been in the game for so long, I have NO idea how many exchanges I'm allowed. I thought when I was young it was around 15 but I tried my absolute hardest the past couple days and still got up to 30 or so and I was hungry all day! I'm waiting to get my blood levels checked and find out but the doctor can't get me in for a while.. I know my Phe levels wil be insanely high probably even from just lack of knowing what I'm doing anymore. Does anyone know how many exchanges an adult can have daily? I would really appreciate it.. This is only Day 3 and I feel like I'm barely eating.
