If all the above posts don't work and I would try STEEDS TWICE before giveing up.
Read something boreing like an insurance policy or simular.
And still if none of that works watch Late Nite with ROSIE O'DONNEL
If that doesn't scare you wide awake nuttin will. Then being awake 2 days will help you maybe sleep.
Hope you can get some rest. Been there and it's not fun.
