Thank you for all of your information. Should I try to get referred by my primary doctor or would I even need a referral? I will check out the web site Breanne gave me. Do you guys have your own dietitian or is it through your metabolic clinic. Through the clinic is that where I get the formula, cuz I’m not drinking any right now and I’m aware that I have to start. Thanks for your guys help. Breanna you are knowledgeable in Pku. I am amazed on how much you know. Me I’m a 30 year old and I don’t know Jack Crap! Thanks for your help.
