apparently, my insomnia cure was used for brainwashing in korea. :(
the lida machine has been considered obsolete by (then it was the) soviet union (since before it stopped existing). it has a u.s. patent, but "has never been sold here."
some doctor managed to get one to test (after it was considered obsolete). he was making his cat take a nap when someone passing by recognized it from having been hooked to it in korea.
the doctor did make some people go to sleep as well believing it would be safer than drugs.
