I don't know where to post this sorry if it's in the wrong place. I should say I'm not being paid to say this but I've had a major win at home this week and wanted to share.
I bought a kSafe off Amazon www.thekitchensafe.com/ It's basically a time delay safe. You put things in it and set how long you want it to lock for and that's it. I got it for my hideous smartphone addiction as my kids have had enough of me on it 24/7... me too. Well it's a bloody marvel and has changed my home life this week, I've been so much more 'present' at home and haven't been tempted to go on my phone as I know I can't have it. The surprising thing was that for the first time in months I stopped thinking about my phone/social media/email. There are other factors as to why I have this addiction and am working on them but willpower alone wasn't working.
Downsides are that there's no override facility other than smashing the entire thing, although I guess that's the point. Also it's crazy expensive (£45 
) but figured I'd give it a go as it's big enough to use for other things... games consoles, cigarettes, chocolate biscuits, credit cards whatever's your poison...
Hope this might be helpful for someone else x
