I have a bad habit of scrolling through Facebook (mainly groups I follow re my pets and exercise rather than friend's posts) and refreshing the "active" and "I'm on" pages on Mumsnet.
I find it makes me anxious, it takes up so much time (an hour can have passed in a flash) and it is addictive.
I sometimes do it while watching TV and I'm trying to make myself stop as no good comes from it.
Anyone else trying to cut out this habit?
