You might ask your doctor to change your
treatment protocol somehow; different type of
interferon (
Pegasys to Pegintron, perhaps). The last time you did the treatment were you fully compliant with meds; did you take the ribavirin and interferon on time as scheduled? It might benefit you to increase ribavirin dosage if possible, dependent on blood values.
In short, something should probably change in regards to your medication to expect a different outcome the second treatment.
