I should think the main outcome of all these studies is not which agonist is the culprit but the fact that by changing or stopping the involved agonist, the compusion diminishes or stops. That is the important part. Other side effects are not so easy to get rid of unfortunately so why argue the fact that some compulsive behaviour can be due to agonists and something can be done about it? Compulsions take many forms Maryse ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
