What drugs are you taking? Mind when I hear drugs I think of Meth, cocaine, LSD.... Most likely you have a viral infection, or a flu. There are no treatments for the flu other than treating the symptoms. If OTC medicines for cold and flu (thera-flu, Ny-quil and many others found here: http://coldflu.about.com/od/overthecountermedication/tp/multisymmeds.htm ) do not work then you need to see a doctor. There is no real treatment for the flu - there are antivirals given in some cases, these do not kill the flu but lessen its impact and is used for at risk patients - those who can easily succumb to pneumonia or be killed by the 'common' flu. there are more powerful prescription medications that a doctor can give, they are in essence the same thing as the OTC medications but only more powerful, some with narcotics to help you sleep. Flus last 7-10 days with onset of the symptoms usually being moderate to severe and symptoms lessening in severity 3-5 days out from onset. Many patients complain of extended fatigue and even muscle soreness up to 2 weeks after a bout of flu. A fever of 39.1ºC to 393.8ºC (102.38 ºF - 103.64 ºF) is not that dangerous for an otherwise healthy adult. although a pain to deal with, usually during the course of the flu no further damage is done. If your fever spikes (rises) to 40.5ºC (105 ºF) see a doctor immediately - as in same day clinic or the Emergency Room) at this point I would advise seeing a doctor either same day clinic or next day appointment. You really need to find out if you do have the flu or something else. A Short list of infections that cause or can cause fever: Colds, tonsillitis, otitis media, the flu, bronchitis, tetanus, measles, mumps, chicken pox, AIDS, pneumonia. Other things like leukemia, arthritis can also cause fever(s). Knowing the cause will go a long way in knowing how to treat the underlying cause thus the fever itself.

Fever is the body's way of killing germs. Its best to let the fever do its job.
