Or it could be because the
Prozac is working but not well enough, so the drug is augmented. Or, it could be the
Prozac has stopped working and you don't need another drug, you need either a higher dose or it's stopped working and you need to taper off and try something else. So that's the first issue. The second, side effects, is impossible to answer, as different people get very different reactions to medication. What bothers you might not bother me.
