With regard to brain fog? Brain fog has many causes. Some of them include fatigue, poor nutrition, stress, fatigue, depression and anxiety. It should be treated by addressing the underlying condition. Toxins can also be the cause. If you suspect that your liver may be the cause, you should be doing liver cleanses. Actually, with your condition you should be doing cleanses anyway, and if you haven't, you may want to look at the protocol I linked to in a previous post. You also mentioned that you were under stress. How much stress? This could also be the cause, so one can't know for sure. Everyone is an individual and has different symptoms for different reasons. A blanket answer does not cover everyone. So my suggestion would be to treat your hepatitis, liver cleanses of which are a very important part, and you may find that as you feel better the brain fog disappears.
