It is going to be very difficult.
However, in addition to the good drugs, there's always my Game Boy. I have copies of Road Rash and Bust-A-Move 4 ready to roll.
Contingency plan in case I end up in there for more than just overnight will include packing the PSOne, cabling, and Syphon Filter 1 & 2 in an "emergency bag" that I will instruct my mother to bring to the hospital. I'll just unplug the telemetry equipment and respirator of the patient in the next bed if I have to to hook it up to the hospital room TV.
The hard part will be no online access. Hell, I even take a laptop to conferences and stuff with me and pay the damn phone surcharges at the hotel.
I have a friend who works at the hospital where I'm having my surgery. If necessary he'll hook me up. I'll see to it.
