I put the kitchen timer on, so after an hour's 'tea break' turn off everything - my laptop - the TV and heating too. I don't use social media on my phone, as I don't want to join the many phone zombies wandering about locally. It must be so crippling, having an addiction to social media, constantly on duty with all the sites open, watching for the next post 'needing' your instant attention. My friend is a complete slave to WhatsApp, always on the alert (like an athlete on the starting line) for that little chime to call her back to her phone. I make her leave it in her car, when she pops in. She can go out to check it whenever she likes - but it's not coming in. I've told her I won't tolerate the rudeness of her constantly looking at that screen - or enable her mental illness with it. No screens for anyone at the dinner table either, they stay in the hall!
