I just took a look at the symptoms for flu last night on flu.gov:
http://www.flu.gov/individualfamily/...oms/index.html
Nausea/vomiting seems to indicate swine flu (H1N1) rather than the seasonal flu this year. I also just saw a report on the news that said the seasonal flu really hasn't hit yet and probably won't until December/January. So if you have flu symptoms now, it is highly likely that it is H1N1 since it is widespread now. Most people are recovering just fine at home. But if I were you, I would go to the doc as a precaution. See if he/she thinks you should take the antiviral they are giving for it (Tamiflu or Relenza)... especially if you are in one of the high risk groups (kids age 6-24, pregnant women, anyone with a condition that makes recovery more difficult (ie. asthma).)
I hope you are feeling better soon!!!
