you need tylenol to break the fever.
and unfortunately, the flu is a virus so you really can't do much but treat symptomatically and get plenty of rest/ water.
airborne/emergenC is a good idea because you'll get the vitamins you need.
try claritin and advil cold n sinus for head congestion. If you have a sinus infection (and you will know because your snot is green/yellow) take anything with guiafenesin in it, it should help drain them. not sure if you can get it over-the-counter.
When it moves down to your chest, do mucinex. When it turns to a cough, thats when you do robitussin.
sore throat- gargle with warm salt water.

hope it helps. getting sick ****ing sucks. best thing you can really do is sleep and eat.
