First of all, if drinking lots of tea and lemon might mask the presence of HIV in your blood, then something like that would by now be common knowledge and it would be advised to never take that before doing a test(and there is no such advisory that exists). Second of all, you asked the doctor and the doctor told you that you have nothing to worry about! So how much times do you need to ask an expert before you are satisfied?? The test came back negative and you havn't had sex in two years.. I think you can safely say that you are free and clear of the HIV infection, so stop worrying. Seriousely though.. if, after all these people replying to you and attempting to put you at ease is not enough, and you are still going around asking people if you should be worried... then I would consider you to be a bit of a fool. Or you may suffer from hypochondria and you should be more worried about that. Anyway, you dont have HIV or AIDS, so go away.
