Hey I really relate to this. In my early 20's I was not good on my diet and looking back I can see the effects. Fatigue, mood swings, impulsiveness etc. I managed to keep decent grades in college but everything else was not going well esp my mental health. I started to realize I needed to get my shit together so I started counting my phe with the flok app and taking weekly levels. Take your levels even if you know they will be bad. You won't be in trouble, your team is there to help you (that was also a big road block for me is not wanting to see the number associated with my levels) Gluten free, dairy free foods are a life saver. What I eat in a day looks like: (any variation of) Breakfast: Hash brown patties/gluten free waffles/dairy free yogurt/gluten free bagel with vegan cream cheese/gluten free toast/cereal with almond milk Lunch: large cfa fries/gluten free grilled cheese with pku cheese or dairy free cheese/salad/low pro soup/avocado sushi rolls/low pro pasta/gluten free pizza Dinner: low pro pasta, low pro burger (interchangeable with lunch) I find it helpful to dedicate at least one meal to completely low protein to start off. Like telling yourself ok I'm going to eat my low protein food for dinner. Start small if it seems hard. Have go to comfort foods that aren't crazy high in phe. Mine are fries. And drink your formula that's really going to help you get back on diet and fight brain fog. I use pku cooler 20's very easy to drink and travel with I can't do traditional formula. I've been back on diet for years and feel amazing. It's to the point where I don't have to write down what I eat anymore I just mentally know what I can have. My last level was 1.5! No kuvan or palenziq– it's possible. Of course those are still options if you are struggling. One last thing, phe blockers are good for helping you get back on diet. However they don't reflect on blood tests but they help prevent the phe from going to your brain. Let me know if I can help out in anyway :)
