Since mostly quitting TV, I find that on the rare occasions that I'm in a situation where TV is present, it seems strange. Shows that my friends rave about are boring to me. I don't crave turning on the telly when I sit down on the couch, and the amount of free time I have has increased quite a bit. As @Joseph Maynor said, TV is a great way to gain weight, as I can recall many nights pigging out in front of a screen. Seems like television and junk food just go together.
I definitely think it would be to your benefit to either cut TV out of your life completely, or significantly reduce the amount of time you spend in front of a screen. Perhaps only watch educational shows, or have a specific time slot during the week dedicated to relaxing by watching TV.
Good luck friend!
