Help with my Diet

Dr. Jeff,

I was hoping you can give me some advice about my diet. At this point I can not handle any sugar at all, not even one gram. If I eat anything with any amount of sugar or starches at all, my face breaks out in hives, my body itches uncontrollably, my hair falls out etc. I have been living on chicken and eggs for months and my kidneys are shutting down from dehydration from the excessive protein intake. My BUN is very high and my urine is dark yellow, despite drinking 80 ounces of water a day and I'm only 90 lbs. Do you have any suggestions at all because I don't know what else to do.
