Since medicines affect people in very individual ways and since their effects can be influenced by other medications, alcohol, drugs, and general health conditions there is no way to tell you which medications might lead you to make bad decisions. There are definitely medications that can cloud our thinking and therefore impair our judgement and others that might leave us feeling very agitated and restless leading to impulsive behavior. If you have concerns about a particular medication get back to us and we'll see if we can give you more information.   Rick Wirtz   Rick Wirtz is a Psychologist, not a psychiatrist or medical doctor.
