Anyone out there has had to make a decision on 1 or the other for treatment of Hep C? I have been vaping for 7+ years with no abnormal liver tests. I'm a grade 3, Stage 4 liver damage(cirrhosis) on biopsy. My question is until recently I have been doing ok until a couple of weeks ago & had a flare up, nausea, vomiting etc. & was hospitalized. ALT = 1000 & AST = 700+ & viral load of 2 million. Has anybody, close to My stats, used Harvoni with any success? Is it worth not vaping for almost a year to go through this protocol?
