Hi
Yes I too have problems with tv, computers etc. and have tried limiting viewing to retrain the brain.
This has worked , but like Mark says it takes a while to take effect.
I started with 10 mins then slowly built up to 2 hours +.
This has taken months with some set backs, but now I can watch most of my favourites, which is great.
Also I never watch anything violent or scary, as it would put my brain in overload.
Just simple easy to follow drama's with out to many car chases or loud music .

Good luck with that and hope you see some improvements .
It will take time however but hang on in xxx
