I had the PillCam done last year. It is very easy. the only prep i had to do was the day before i could only have liquids and then nothing the morning of. They strap on the device and give you the pill and off you go for the day. My only restrictions after taking the pill was i couldn't drink or eat anything for 2 hours, then i was ok. There is a little light on the device that blinks and as long as its blinking the pill is still working its way through. Once it stops blinking it has passed through and you can go back and return the device.
It was funny in a way because i had it done in winter and when we went out i put my jacket over it and people just thought i was pregnant. when we went to lunch and i took my jacket off i did get quite a few stares :)
