While pushing the pain pills don't forget to drink water and to get some roughage. Those pills sometimes back the system up. The combination being blissed out, half asleep and watching the pretty pictures (or gnomes, as the case may be)often means people forget to drink and eat regularly.

Things back up far enough and long enough and they have to open you back up with an apple corer and clean you out manually. Not a pleasant experience. A big glass of water and a bowl of oatmeal couldn't hurt.
