I never had chronic nausea due to HCV.
SInce your biopsy was very recent and you're a stage one after some thirty years of the virus, maybe looking elsewhere for the source of the problem is the way to go.
Nausea has many causes and 2476 of them are listed here (not all chronic):

The site below says chronic nausea can affect 25% of the population, which surprised me:

I myself would look elsewhere before pinning it on HCV, since it's 'behaved' all this time and you remain a stage one after decades.
If you decide to treat the HCV, it would be best to resolve the nausea before starting, if possible.
Maybe try the MH gastroenterolgy forum as well. Here's the gastro expert link:
