My mother was diagnosed with hep c many years ago. She tried the Pegasus and Ribavrin combination and it did not work. Her hep c is in stage 4, not sure how bad her liver damage is because she will not disclose. However, she has is still drinking daily while on the treatment. She won't listen to me when I explain to her that it is not healthy for her to do that... what should I say to encourage her to stop drinking?
