Ask Tamar...how to break my iPhone addiction?
Change how your notifications come up - who knew you could turn them off completely (begone, taunting red alert telling me I have 4,904 unread emails), or have them just appear in your 'history'.
Then go completely rogue and delete all social media apps - so you have to access Facebook, Instagram, twitter etc from the internet browser. More clunky, less enticing.
Keep your phone on silent, and turn off vibrations.
Buy an alarm clock - and charge your phone outside your room. So you won't get distracted at night. Could be a lot more fun.
