A couple things I noticed about abstaining from television.
First, I am getting way less sleep than when I watched TV. I used to watch tv right before bed, and it would put me into a sleepy mode. I'd be either dozing off or I had slept 20-30 minutes in front of the television before bed. So it was a good transition for me before bed. I'm missing that now and I find it takes a lot longer for me to fall asleep. And as I mentioned, I'm missing those naps I'd have when I dozed off from watching TV. I tried to take my usual "2 hours of napping in front of the TV on a Sunday afternoon" nap in bed today and really couldn't get it going.
Second, I have a way lower inclination to cook. For some reason, because I'm locked up in my room now (my room has the best lighting in the house and it's the warmest room) all the time, and when I'm in here, I have no inclination to go out of my room. That includes going to the fridge to grab a snack or drink, and henceforth, to cook. I have not cooked for myself since Lent began. I think part of it is that I used to cook and enjoy my meal in front of the TV. I could eat slow and enjoy the taste and the show. Now, I just stare into nothing and eat. It's depressing.
So I would say that at this point it's working, because I'm suffering and that's great because I love to suffer. In previous years, giving up gaming or chatting, there were alternatives. But by the end both those Lents, I guess I would say that I had gotten used to it. However if you think about Christ's sufferings, I don't think you can ever "get used to" someone whipping you with a mace. It's not like after 3 hours of flogging you think "Hey, this isn't so bad.. I think I'm getting used to this.."
Praise God for allowing me to find a way in which I can find suffering such that I can be constantly reminded of His sufferings.
