HBsAG/army/FFL/medicine?

I tested positive for HBsAG i got exposed to the virus when i was just 1 hour old but never been sick, and my liver function and everything is fine. Is there any medicine or treatment that might help me or maybe if i am lucky i wil lose the virus ? I've never infected anyone my doctor in iceland says that i am gettin better and better and might get rid of it some day. But am I then chronic ? and i am immune i know i ask alot...
