It was also a medical bit! Possibly around the same time - the doctor tells her there are no medicines that prevent migraines (?) and as she's depressed already he'll give her beta blockers to stop the seizures (beta blockers have no effect on seizures, are used to prevent migraines, and have depression as a significant side effect). He then adds that she should take feverfew to detoxify her liver or something similar. I was left with the impression that the author had taken some very brief notes some years earlier and then attempted to reconstruct things from them.
