Start taking vitamin C; 1000 mg every 60 minutes until you go to bed tonight. If you wake up during the night, take another 1000 mg each time you wake up. Vitamin C helps to bring a fever down. At this amount, you may get diarrhea, but this is beneficial to the body when you’re running a high fever.
In addition to the vitamin C, you can also take an ibuprofen to bring the fever down, but once it’s down, stop taking it and stay with the vitamin C.
Drink LOTS of ice water while you have the fever and lots of regular-temperature water after the fever drops. The vitamin C will act as a diuretic so you’ll have to replace the water.
If your fever drops, you can continue to take 1000 mg of vitamin C every two hours and extra doses if you feel the symptoms getting worse.
