Usually I fast on Mondays.
Bread and water from the midnight before. If I say a Rosary for the Poor Souls then I can eat after 6 pm.
If I do a second fasting day it’s usually Thursday. I can do another bread day or else an egg and grapefruit day where you eat 2 plain eggs for breakfast and a grapefruit for lunch and then say a rosary and eat dinner after 6 pm.
Sometimes I move the 2 fasting days to other days because I have to do intensive work stuff or drive a long distance on the regular day, and it’s not a good idea for me to fast while having to work long hours or drive, because I fall asleep. Like this week I moved the Monday to Wednesday, because I spent Monday in a 12 hour mandatory class for work and I would have fallen asleep if I ate bread and water.
Also I never do 2 fast days in a row because it starts making me ill. I have to be careful as well to make sure I don’t pass out if I happen to go to a Mass in the late afternoon or evening before I can eat dinner. I have had a lifelong problem with sometimes getting faint at Mass if I haven’t eaten enough, especially if I kneel a long time.
Fridays are meatless.
