tamiflu i recommend always having it on hand. you can buy it online from a pharmacy, stick it in your drawer just in case..
noodles has a good recommendation also i would recommend colloidial silver which can be bought at any health food store. it will boost your immune system as well. works very well but works best at the first signs of your viral infection.
if you are on cycle continue taking support supps but stop all injections and orals until you feel better
