what was it prescribed for?
i take 300mg for depression/bipolar. it took several months to take full affect but since i've been on it my depressions are much less often and less severe, so it has been very effective for me. i haven't noticed any side-effects, either.
it hasn't done anything for my SA (though it wasn't meant to).
i've also never read of another case where it has helped someone's SA.
