Lent and all that..

I gave up giving things up for Lent years ago.

Partly because I'm not religious, but partly because it's usually counter-productive. If you give something up completely for a few weeks, you're more likely to overdo it after (or on Patrick's Day if you allow yourself to take that day off).
It's like going on a crash diet, then breaking and binging.

If you're eating too much unhealthy food or drinking too much, you don't need to give them up completely (unless you think you're an alcoholic).
Just cut down on them for the whole year, but still allow yourself to enjoy them.

Also, if you're cutting something that's bad for you out of your life, what good will it do you if you do it for 40 days out of 365/366?
It would seem much more sensible to me to have a forty-day period of complete indulgence, with moderation the rest of the time.
