Resurrecting this thread because the last episode of the season is on Tuesday night, and also because I saw the supply list here:

and wondered what others would bring for their "one" personal item.

For me, it was a bottle of high potency multi-vitamins. Or maybe a bottle of Ibruprofren, or maybe a bottle of rum (the girls seemed particularly fond of it).
