Propofol: anyone with experience?

My wife has transformed migraine. Also allodynia, and dystonia of the neck (possibly aggravated by successive courses of occipital and trigeminal nerve block injections). Triptans once helped some, but no longer. Same with ergotamines. However, on two occasions during the past year while hospitalized in connection with other medical procedures she was administered propofol as anesthesia, and when she regained consciousness, her migraine was gone. And did not return for over a week -- for her, a long period of relief. Does anyone else have any experience with propofol as a migraine abortant?
