not a whole system, just one thing. i game late and used to keep a cold soda next to me, then another, then another.
rule: if i want a soda after midnight, i have to finish a full water bottle first and wait 20 min. that's it. half the time the craving is gone, other half i have one soda and stop.
i also stopped keeping them in the desk mini fridge, so i have to go downstairs like a raccoon. last 6 weeks i'm down 9 lbs and my sleep is less garbage. not saying it's magic, it just broke the autopilot. anyone else have a tiny rule that works better than a big plan?
