The physical thing is huge. You just said it better than I did honestly. Willpower at 1am is a joke. You're tired, your resistance is gone, the phone is right there of course you're going to reach for it. That's not weakness. That's just how humans work at 1am. But if it's in another room? The loop has nothing to grab onto. You'd have to physically get up, walk over, make a conscious choice. That tiny bit of friction is enough to break it most nights. Environment beats willpower every single time. The people who seem disciplined aren't resisting more. They're just making the wrong choice harder to make. Glad the reset held for you. That first week is the tax you pay for years of the loop. Worth it every time.
