On several Stargate Atlantis and late Stargate SG-1 episodes they spend a very long time on a jumper. For example, in Atlantis 4x17 "Midway", at the end, Bill Lee, Kavanagh, McKay and Shepard are on a gateship for more than a day
after Midway is destroyed until the Daedalus picks them up in intergalactic space
But there's no apparently place for a head (toilet).
I'm familiar with Nobody Poops (not putting TVTropes link as a public service), but this is a little different because usually you can imagine it is somewhere but not seen. In a jumper, there is literally no place for it. Because of this unique case, and Stargate's propensity to break the fourth wall, I'm wondering if there's anything out there.
Any discussion by show personnel or any canon information? And I'll even just take a tongue-in-cheek "Man's I gotta take a leak real bad" when someone returns to Atlantis.
