Not everything has to do with Hepatitis C. Blurry vision has many causes.

Hi. What is your genotype and what did you treat with before? This will help us be able to better answer you.
I first treated with Interferon in the 90s, so, yes, before my most recent treatment I did have brain fog and fatigue. Experienced that on tx, too, but I believe the Riba I took added to the brain fog because of the anemia it caused. Now 6+ months post tx and brain has cleared up a lot, and the fatigue started going away with in a couple or 3 weeks after tx.
