I've found the answer for you, no drugs required. You could probably even run it at home, set it up to run for say 24 hours, wake for 30 minutes to eat and drink and use the toilet and off you go again.
That is actually a very interesting discovery. Its miles from being available in home but this could be the answer to insomnia that many of us have been waiting for. I'm not willing to have electrodes implanted into my brain but if they could set it up from outside somehow, I would buy a unit for sure unless they were grossly expensive. Perhaps a focused beam of the right frequency radio waves or a high intensity magnetic field with the correct modulation, some kind of way.
