Yes, this has been discussed lots of times over the years. (I don't remember Sinemet and drooling being discussed together.)
If you go to the search page*, type in "drooling" as a keyword. You get lots of results. But, if you type in "robin" as author. You get a manageable number of summaries to scan.
