I don’t hear anything that makes me concerned about HIV infection. Have you had sex with people who might have HIV since your test in 2014?
Your boyfriend could certainly be infected and not know it – either years ago or by you. I think it might be wise to get him tested because if he is positive, you no longer need to worry about this issue with him.
Can you tell me about the outbreaks that you are experiencing? It is pretty unusual for a herpes outbreak to clear up in 1-2 days, actually, though I suppose with suppressive therapy on board that might be. Also, exactly how were you diagnosed? Blood test, swab test?
Sometimes frequent sex is a trigger for outbreaks, that could be the case with you.
Suppression doesn’t completely eliminate outbreaks, but it does shorten them and reduce the frequency with which you may have them.
When you say you have doubled your dose, do you mean that you now take 500 mg twice a day or 1000 mg once a day. Twice a day might be better in your situation to keep drug levels very steady.
