There is a chance, 1% of people naturally clear HBSAG every year. Not sure why you were given
Truvada, that is a combo drug for
HIV. You should have only been given Tenofovir. If you want to buy drugs for cheap, buy them from India, you can even get Vemlidy for really cheap out there. Post your entire history here, maybe you could be a candidate for stopping treatment, for example if you were HEBAG+ before and then became HBEAG- and undetectable on treatment.
