Hello Hopeful425,
It takes a week of so for the drugs to wash out of your system. There is quite a lot that goes on during treatment and some people do take a while to come good after.
That said, the average age of a patient is 55-60 and at this stage in life all sorts of other things begin to happen. Thyroid problems and diabetes are common at this age and 3 x more common in patients with Hep C so it’s worth having a “routine physical” type appointment, maybe with a doctor to whom you don’t mention the Hep C so they can look at you with an unbiased eye.
