What is there to REALLY be afraid about? Its better to KNOW for sure if the mania was prozac caused because that is something youvseriously need to know for yourself if that is what happened. You need to log ALL negative effects that meds cause you. Shoot, my pdoc tried a bery tiny low dose of lamictal & i btoke out in a rash & itched all over. I finally had to give up on drugs all together becausevthe side effects were so bad & fearedbtrying anything new without being hospitalized.
