Still using this for posture, and my posture is improving (though it's confounded by the posture brace I bought a while back, which seems to actually work). Not using this for standing/sitting; instead I now stand most of the time, and only sit while doing the highest-value thing I could be doing (which is usually ugh-fielded and unpleasant). I've given up on regulating my sleep schedule.
Other things I currently use the food-reinforcements for:
CoZE. For those who haven't been to workshops: this is an awesome CFAR invention; rejection therapy is a subset of it. I walk around with a bag of chocolates while doing this and reward actions. After accumulating a certain number of CoZE points, I allow myself to eat whatever I want for the next couple hours.
Reality checks for inducing lucid dreams.
I have an hourly mental ritual that involves a bunch of visualizations that feel like they should increase agency and do other things.
Coming up with useful new ideas.
Taking supplements.
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
