You're so unfortunate that you're suffering with this problem,
Usually hepatitis B is a self regressive condition which goes of by itself within10-25 days. Yea there is no proper treatment for this as a matter of fact. But you can help yourself by taking lots of water and taking rest. Avoid oily, spicy, non veg, eggs for 1-2 months have only bland soft diet and it will be very helpfull to you. Since you're suffering with a problem related to liver your appetite may go down but do not skip meals force yourselves to take something or the other. You can have fresh made fruit juices, clear soups, curd, milk, fruit, vegetable salads etc.. Avoid alcohol and smoking.
Take care of your health
