Anyway, he was recently musing about the latest ketamine-for-depression research, and wondering if this notorious drug could someday have a clinical use.
I wrote in to tell him I use it (clinically) quite often -- not for depression but for procedural sedation.
To my surprise, he printed the letter. And now I wish I had included more from my informed consent spiel, mentioned the sialorrhea, and maybe talked about that one time I pushed it too fast...
