Day 7 - hit the wall

Day 7 and I have hit the wall! I have been constantly light headed for the past few days, and have developed a sore throat. I had that sensation that shelley told me was the liver/bile duct (discomfort in upper esophagus) so I used some fresh lemonade sweetened with fruit Sugar to do a flush. It definitely helped, but then I got the dreaded "butt pee" ... also a deep Depression has set in (this is very unusual for me. I am normally a very positive person.) I can't even think straight ... am eating a fairly normal diet .... have hit the wall... HELP!
