Don't worry i had it it wears of 3 days without virals usually for me it went after 5 days but even if you feel better KEEP taking the tablets until the 10 Tami Flu tabs are finished! and try drink lots of water and don't take acidly stuff or any orange juice try ginger ale. try eating very little and drink tons of water. I started feeling much better when i drank water and try take your tablet with food so you don't vomit don't worry if you did on the first day its normal, also you will probably sleep for shorts hours as well remember WATER! sorry for using caps just stressing the importance! take care hope you get better.
