Hi Vicki,
Are you going to a Hepatologist or Liver Specialist? Lamivudine is the worst thing you can take for Hep B and your liver. This is used mainly for HIV Patients. It's had some very bad side effects on Hep B patients, even causing HCC and in some case, DEATH. I am glad I came here when I did before it's too late. Here is an article:

Your only two choices should be Tenofovir (Viread) or Entecavir (Barraclude). Nothing else should even be an option for Chronic Hep B patients.
Please either have a talk with your doctor, switch doctors or see a Hepatologist or liver specialist (try one at hepb.org). This is not safe for you! God Bless
