Should be out of here today 

Barring a last minute cockup I will be out of here today.  I cannot stand another night in this death chamber.

It is really hardwork being in hospital. They tell you uninterrupted sleep is important. In hospital you do not get that. The most you can hope for is 4 hours at night. You are woken up at 12 and 4am for various reasons. By morning you are exhausted.
