I am trying to take a break from this site.

Good luck, hope it will work out for you!
Not sure what would work best since for some if not cold turkey it won't work and for some, reducing step by step is the way to go.
Is there a specific reason why you want to reduce screen time?

I would slowly phase it out. First, I'd only visit SG once per day. Then just once every two days, then once a week ...

Best of luck! I hope reducing screen time gives you some peace of mind, or a new perspective, or any other goal you're looking to achieve.

I don't have a job where I have to use a computer or a screen so it helps but I can see friends and loved ones struggling with reducing their screen time.
A friend of mine has had some success with setting a maximum time (with an actual timer on his phone and PC) and he gets an alert when he gets close to it. He doesn't cold turkey but he usually turns off his devices, and go out for a run or something and he leaves his phone behind.
If it's raining he just puts some music on and meditate. He found it helps him not go back to the screens.

If he has time left after he is done with work, he plays games or browse but he noticed that he is being "less wasteful" when it comes to "fun" screentime now.

I don't know if that would work for anyone really. I think you're right in trying to cut down and SG of course tends to bring us back to check what's been posted etc. It makes sense to want to cut back on that and I think you can do it progressively.
I hope you still come around to give us a hello from time to time but no pressure and good luck on your journey.

So how did it go?
