Yeah, I know what you mean! I was gonna post that same thread yesterday morning but this is what I did instead. I've been trying to cut back - try this:
You click at the "Thread Tools" at the top of the thread which interests you and where you post all the time (e.g. Neighbours, etc), click "Subscribe". Do this to all your "vital" threads (I had 7 of those, plus 3 my threads, plus 4 where I posted recently). Then when you log in, click "Control Panel" and it will show you which of those threads have been updated. If not, I close the website. If yes, I read the new comments and answer them if I feel like it. Twice a day (like now) I allow myself to browse all forums and read everything - this SUCKS because it's warm and sunny and I have friends and I'm on holiday, but I sit here and read about someone who's pregnant whilst it has nothing to do with and I won't have to deal with it till I'm married...
So yeah, try this. I always despised people who are addicted to internet, and now I'm one of them... Good luck!
