So far I win (sorry, but the 5 month period was not from a doper so it’s disqualified). When I first got on birth control pills again last spring I had a period for over 2 months. Then I went back and they put me on a different pill and that sorted it out.
My 11 day period was my longest “natural” period… I also had a 17 day period when I miscarried…
In that vein, check out the new ChromaKey album. Graveyard Mountain Home, which is synched to and partly sampled from an old how-to-deal-with-the-anger-when-mom-dies-and-leaves-you-with-evil-stepdad film. The “special edition” includes DVD. It’s creepy, and oddly moving. Particularly with the lights out.
