it takes me hours to reconnect to my body and stand up in the morning
   after sleeping.
   some years ago I searched for a device that would push me out of bed.
   somebody had made an "ejector bed" but they weren't selling it.
   I bought a cheap high-torque motor more recently. I don't know if it's
   strong enough to raise plywood with a person on it, but it seems to
   make sense to try.
   the motor also has a bracket to help with mounting, but more parts may
   be needed.
