the flu is definitely no fun. Keep pushing those fluids and try to get some rest. If you still have a fever, call your doctor, just to be safe. A fever shouldn't last longer than a few days and if you're already into your second week, then it's time to check with your doctor. You may need a prescription to squelch this thing if your immune system is too weak to fight it off.
If your throat is sore, drink lots of hot/warm tea with honey. Honey is naturally soothing as well as having plenty of anti-oxidants.
