Dark Light,
I have been thinking about fasting/abstinence a lot lately, with Lent coming.
I typically eat in a way that is now considered “fasting”. The nature of my schedule, and the fact that I cook for other people for a living, means that a typical American Breakfast, Lunch & Supper schedule does not work for me. As a matter of fact, I cannot think of the last time I actually ate a ***meal, ***meaning more than one course/item at one time, sitting down, that was not grabbed in between running from one job to another.
I also typically do eat eat that much meat, as I cannot afford it- same with fish, except maybe for canned tuna. I do lots of pastas, cheeses & veggies, and fortunately, I do sometimes get left-overs from one of my jobs, which is about the only time that I really eat meat, and it it usually because it will get thrown out instead of eaten.
So for me, although I am obedient to the “rules”, they actually really don’t
mean anything for me, becasue it’s not really any different than how I live the rest of the year. So, a couple years ago, my spiritual director & I came up with a new way for me to customize my fasting/abstinence experience for Lent.
One year, I gave up coffee. For some, not a big deal- for me, I would have rather worn a hairshirt and used a cilice!

And it was not a lot of fun for the people around me, either! :bigyikes:
I will say though, my coffee drinkg habits are a lot different, and my prayer life is better, because I “sit still” easier.
One year, it was TV. I had a very bad habit of having it on all the time, even if just for background noise. So instead of watching TV, I read a book that my spiritual director suggested and followed a more intense Lenten prayer/retreat program inspired by the Spirtiual Exercises of St. Ignatius.
Again, a very difficult thing for me. It made me realize that I feared the silence, because it was when I was silent that I heard the stirrings of my heart calling me back to God. And that meant looking at how I spent my time. At the end of the day, was my day spent for God’s glory or for mine. That was a very sobering Lent. And much good has come from it. I relish the silence now!

And I make it a point to have at least a half an hour of it every day!!
Sorry to have rambled, but I wanted to give my experience and say that I understand where you are coming from.
Peace be with you on your journey!
