Wow Im really happy for you!! You must have a very strong immune system.
I don not know exactly when I had it, however my doc. estimated more than five years. And I did not use any chemical medication.
All the best
How long did you have HBV? If you did at all what treatments did you use?
you had hbv and cleared
hbsag gets low after long time because the main antibody is hbcab and sometimes hbsag gets lost.
if you like you can take a vaccine to increase hbsab but it is not needed unless you find some detactable hbvdna
