For Hepatitis B: Have been taking viread for about 8 years, have had good results so far, load count has been undetectable for almost 7 years. Have discussed stopping medication totally with Doctor, decided to continue with treatment for another year then see where I'm at then, only side effect I've had is lack of energy. I'm already taking meds for depression, but had to increase dosage within a year of starting viread. Don't know if meds were reason I had to double my dosage for depression |

For Hepatitis B: I have been taking Viread for 6 years. My Hep B viral count has remained undetectable for 3 years now. However, I need to continue Viread in order to keep the virus in controlled. I have chronic lower back pain (for 3 years now) that continues to worsen. Exercise and rehab does not help. The pain has gotten to the point where it is affecting my daily living activities and I'm only in my early 20s. I also have very bad insomnia. Hope we will all be Hep B free one day. Will take a miracle, but believing is half the battle.
