I'm not sure who Manda was asking, but recently, my function is fluctuating between 18 and 14%. I don't seem to notice a difference in how I feel based on my function percentage, but rather, over he last few months, as time goes by I feel worse and worse on a steady course downward. It must be my body telling me the toxins in my system are becoming too much. As for protein loss, I'm dumping about 1800 mg/24 hours. My lab's normal range is 40 to 220. I've been eating very little protein (at the most, 20 grams a day) over the last 6 months due to a gradual aversion to it, so god only knows what it would be if I was eating like I used to!
