For a few days, so that when you re introduce it the rush of dopamine is way more intense. I think it's called ascetism or something similar
The nofap thread got me thinking, when I masturbate every day it isn't anything special after a bit, but taking a week long break from it and then doing it makes that last one 10x better than any before it
Also with dieting, when I eat extremely strict everyday, a cheat meal like some ice cream or a chocolate bar tastes absolutely magical, best taste of my life
I also have done this once or twice with MUSIC. I wouldn't listen to any music in the car/at the gym/laying in bed at all for a few days(harder than you think) and then one day when I'd be in a great mood I play some of my favorite songs and I'm in ecstasy because of how beautiful it sounds.
Anyone else do this with things? It's pretty weird now that I type it out lol
