hey tracie! using juice isn’t too gross. i used to use orange juice on corn flakes a lot, now i’ve just switched over to coffee mate. my favorite is on chocolate cereal (like cocoa puffs) cuz it makes the coffee mate taste like chocolate milk. i really dont get sick a lot either. it cud be in part to our diet maybe. i dont really think pku itself has a lot of effect on our immune systems, but all the fruits and veggies we eat could definitely boost our systems compared to those on the not-so-healthy “american” diet. my mom also freaks out pretty easily if i get a fever. did u know a fever actually causes higher blood phe levels?? so if u get one, take some tylenol or motrin asap!
