I do not practice Lent. However, I am reading up on Catholicism and the practice of Lent. There is a good book by Pope Benedict titled 'Journey to Easter: Spiritual Reflections for the Lenton Season'.
You need to be careful, though. Lent is about making a personal sacrifice to glorify our Lord. Instead of making it personal, people tend to make it very public, letting everyone know what they are giving up for Lent, which goes against what Christ taught:
"Be careful not to do your 'acts of righteousness' before men, to be seen by them. If you do, you will have no reward from your Father in heaven."
