I've been surprised myself to find that what I miss the most is watching TV alone. Last night, I made a very conscious decision to break my commitment to not watching TV alone. It felt soooooooo good.
That one didn't work for me. Ok. I want to watch TV alone sometimes. I accept this. One vice broken 2 1/2 months into the experiment. I could have held out longer but I thought about it for a while and when I finally did watch TV it was amazing and relaxing and refreshing.
