10,000 MG of Vit. C each day - take 2,000 MG and repeat every 4 hrs. - drink tons of water and if you work out continue to through this period. Also the obvious wash hands often and don't touch your eyes or nose unless you've just washed them. Don't use group towels only paper towels or personal towel to dry hands. Make sure to sleep well - 8 hrs.
good luck!
