Actually there is something in Elder Evils, but that's unnatural insomnia caused by an excess of tainted positive energy or something. And off the top of my head, I think there was an NPC who hadn't been sleeping so he'd been using potions of Lesser Restoration for that in one of the campaign modules. Could have been Red Hand of Doom, but knowing my memory it could easily be Shackled City or something instead. Probably not Savage Tide or Age of Worms though.
