We are not giving up anything this year but taking up the Bible and prayer.
The Help wants to read from Psalms everyday. For Lent I will actually remind him. Of course, I can see some logistical problems with taking this on. The Help doesn't think too far out in the future, so I'll need to ask him how he wants to handle those times of the week when the readings won't work.
For myself I will take up one more prayer a day. My days have 4 prayers (3 prayers before meals and our night prayers), 5 would be best. I'm on auto-mode in the morning for any thoughtful prayers in the AM.
I used to listen to a (catholic?) podcast of prayers and I can't remember the name of it. It was something with pray or prayer in the title. I do remember they all ended with "In the name of the father, and the son and the holy spirit, as it was in the beginning, is now..."
Anyway, as a couple we are taking on Lent and trying to make this year about growing closer to G-d and less about losing weight.
