Make an elaborate trap rig involving a piece of rope, 1 heavy mallet, a movement sensor and a clock
rig the mallet up with the rope to the motion sensor, set it to smack you hard in the face if it detects your eyes opening before a time set via the clock, so the instant you wake up around 4am, mallet smacks you hard in the face and hey presto, you'll be out cold for a few more hours!
