Obviously a little distraction and fun is good. But these days it easier than ever to waste an entire day or two watching Netflix and staring at your phone.
It is also worth looking at all these distractions (which turn to addictions sometimes - addictions playing the same role) as means to avoiding emotions which arise when we look at real problems and start to solve them. Somehow our emotions pull us back into this lake of low level, auto-pilot functioning where status quo is maintained and nothing new happens. Emotions trick us here.
More like years, nowadays. Some people (most?) never recover at all, because it's cheaper and more addictive than smoking. Apple's detailed time tracking was a revelation. We discovered that my wife (who is currently out of a job due to COVID) was speding 8+ hours every day on her iPhone and iPad alone, and I myself was spending entirely too much time on my mobile devices as well. I managed to cut down to about 1.5 hours a day. She's still struggling with it. And it's hard. I have to leave my phone upstairs so I don't relapse.
