After feeling lucky and lcukier its time to be unlucky. So the present version of feeling lucky gives an option to unlucckify the queries that have been made lucky. Since, the lucky queries cant be seen on google,you will have to goto the unluckify page after installing the latest feel lucky greasymonkey.
The unlcukify page will remove the query from the lucky list. As soon as the query is removed it is displayed as an alert msg. Although this method works satisfactorily, their should be a more sensible method that does not require going to the unluckify page.
