It's not much different than regular flu. Just take the Tamiflu and slow down.
People in our age group (teens to 40's) are the most vulnerable to new strains of flu. Surprising, right? You'd figure babies and old people would be dying. But that's false. Healthy, young people are most at risk because our immune systems go fucking ape shit and overreact and that's what kills us. So, slow down, relax, and get some sleep. Don't push your body too hard.
You may have H1N1, you may not. But given that you've been prescribed Tamiflu, it's in your best interest to lay down with some chicken soup and relax.
