I just thought about this because sometimes members want to quit the forum because they spend too much time here.
The mobile sleepingbag is a little pouch where you can put your phone inside to remember not to use it. Here in Norway they were giving them away to students. Often the pouch will have a inscription like “take the time back”.
I’m using a pouch that originally are for my reading glasses, but my phone fits nicely inside, so it serves the same purpose.
I’ve only been doing this for a little while, but it seems to help a lot. It helps to draw out your inner child and imagine the phone needs to sleep
Anyways, maybe something to try if you feel the phone controls you, more than you do it.
