Oh you've given me a reason to talk about the Stan twins and sleeping, you're going to regret this
Between the two of them, I am of the controversial opinion that its STAN who doesn't sleep.
Ford knows the value of sleep. He spent however long avoiding sleep as a LIFE OR DEATH type situation (Bill) and THEN spent 30 years in the multiverse in constant danger sleeping only when he could. Ford has had a terrible relationship with sleeping for forever, even when he was a teen, desperate to prove himself, he wasn't sleeping in order to study and read.
Which is WHY, retired Ford? Fucking LOVES to sleep.
Bill is gone. He's on a boat, safe, with his brother by his side and all the food, medical supplies, and resources he could ever need or want, studying anomalies on what is basically a never ending vacation. All this to say, FORD takes naps. He takes naps in bed, at all hours. He takes naps on couches, on chairs, on the desk, sitting upright in kitchen stools, Ford takes naps in the car, no matter what car, whatever. If the place is VAUGLY comfortable and his brother is nearby, Ford is out like a light. The man makes napping an OLYMPIC LEVEL SPORT and he wins it like everything else. The amount of sleep he gets is something to aspire to.
STAN on the other hand. Is the opposite. His sleep was not a constant pull towards factors he could not control, his sleep schedule is as solid as stone and as unending as steel.
Stan runs, fully functional and his ultimate cheery (grumpy) self, on MAXIMUM three hours of sleep a night. 10 years of rigorous sleep schedule to move the car he's sleeping in so he doesn't get his window knocked on by police. Top THAT with 30 years of running the shop during the day, and spending ALL NIGHTS EVERY NIGHT working on the portal, means that Stan's body has given up the fight of demanding more sleep and just thrown in the towel, and Stan gets by with basically nothing
This is, predictably, SUPER GODDAMN UNHEALTHY.
When Ford gets back, Stan sort of. Doesn't know what to do with himself. He's awake, no matter of tossing and turning really matters, he's just. Perfectly fine being alive at 2 in the morning
After the memory gun, Ford is VERY CONCERNED by this behavior, CONVINCED that the not sleeping thing is a side effect. It isn't until Stan gets all his memories back (and after Stan yells at him for hovering) that Ford internalizes that Stan really. Just. Doesn't sleep.
(He learns the reasons for it and has a whole ADDITIONAL guilt spiral on top of the Bill cipher/memory gun one. Stan has to actually wrestle him into the idea that he loves him anyway)
Que Stanford Pines Ultimate Plan to get Stan to sleep more.
Hes a doctor twelve times over, surely this will be easy.
ERR WRONG. Stan is a hard nut to Crack.
Super comfortable bed? No change. Better pillows? Ultra soft blankets? Nope. Weighted blankets? Stan feels too constricted, opposite effect. Darkened bedroom space? Too dark. Nightlight? The blue light makes them BOTH have night terrors. Sleep aids like sleeping pills or dummies? Stan compares them to the drugs the mental institution gave him and Ford hucks them into the ocean.
Stan's BATSHIT sleep schedule is a constant battle Ford has to fight, but by god is he going to win. Eventually.
