It does sound like you are on the "up and up" and you are so exhausted that is seem like it will never end. Watch that cough carefully and if is nose is running you are doing well. I would replace the juice with pediliate (sp?) or non sugary and non acidy sports drink. I can only stand gatorade when I am sick and/or dehydrated.
Continue what you are doing, you are doing what you need to do. Sleep and rest for all is just around the corner.
