Why I Built ZzzSweet
A 20-year night-owl's self-rescue story — meditation, sleep courses, peer pressure, fines… nothing worked, until I built this
3 a.m. — I told myself again: “This is the last time I'll stay up late.”
Tried meditation — the longer I sat, the louder my mind got. Then I just stayed up anyway.
Bought stacks of sleep courses — they played on screen, while I stayed up off-screen.
Asked friends to keep me accountable — they said “go to sleep,” I said “soon” — then stayed up 3 more hours.
Built bedtime rituals, fined myself for staying up — I just got poorer.
Until I built ZzzSweet. No bargaining — it locks on time. The password goes only to my friend.
In 3 months, my bedtime moved from 2 a.m. to midnight.
Not because I suddenly got disciplined — but because it made the hardest decision for me.
