I thought it was bad, or harmful, to use such antirerovirals for short term use. They call it compliance or something like that. Once you start, you're supposed to stay on it. Maybe not forever.... but you're not supposed to go on an off of it.... anytime..... on a whim. Are you? Otherwise a virus strain in your body can build immunity to that drug over time.

In any case, it's a big deal. It's not something to be taken lightly.
