I was told the same as HectorSF suggests above by two doctors, because I was having the same problem with non-advanced virus. Also lots of fatigue. Probiotics for the bloating (good ones) were suggested and helped a little. You might try that.

If your liver is still healthy, then your experience of nausea is not related to hepatitis C. Nausea is not a symptom of hepatitis C and is only a symptom of very advanced liver disease. Most people with hepatitis C have no symptoms (which is why more people has hep C that don't know it then those who are aware they have it) until the resulting liver disease is advanced.
How your had a liver biopsy? It is the only test to diagnose the condition of your liver.
See you primary doctor and get a diagnoses as to what is causing this issue.
Good luck.
