My doctor informed me that the hep B had been cured by my immune system . But now I've been reading that Harvoni is causing a relapse of hep B . I've been living with hep C since 1988 ,tattooing . Only consumed alcohol for maybe 9 months after becoming infected . Had hep B early 70's I.V. drug abuse . I have no cirrhosis , my enzymes fluctuate and i take a nap in the afternoon. I'm in my mid 60's . Is it worth the risk , hep B was BAD
