I had this, and it sounds like you've got the H1N1 virus, although obviously I can't be certain. Easy bullet points:
- It goes through stages, so don't be surprised if symptoms change. For me, it started out with congestion and the indigestion, then moved on to fever and diahrrea before it "broke" and turned into a week or so of coughing. And more congestion.
- As with the above, it takes time, so don't think you're better until you're genuinely feeling much better.
- Stay in. Don't go out unless you have to, and when you do, cover your mouth when you cough or sneeze. It's very contagious, and while healthy folks like most of us will survive it just fine, pregnant women and children are much more vulnerable, so be thoughtful and try to avoid spreading it.
- Drink lots of liquids and get a lot of rest.
- Play Diplomacy online in your spare time. :)
