Bad smells wont work since the pavlovian association will be with the smell. We have to do it through transcranial magnetic stimuli to the pons and Area Postrema, like they do in rodents. In rodents it works perfectly.
Anyone know how to do that? I'd be very happy to vomit in an EEG or FMRI
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.
