Sleep Fatigue

If a player doesnt sleep for 10 in game days they get the effect of 'sleep fatigue'. This fatigue would be similar to the nether portal nausea effect buy much milder, as well as also making the player lose hunger slightly quicker than normal. After 15 in game days of no sleep the nausea effect would be the same as the nether portal and the hunger effect kicks in much like food poisoning forcing the player to sleep.
