This vice and that of lust are closely linked.
If you don’t master this vice, your urges will be much stronger.
Gluttony and lust have a similar feeling of desire.
God, in order to fight pride in you, allows lust.
So be humble and eat fewer gluttonous things and fewer tasty drinks.
To be humble, you have to forgive yourself for your mistakes.
Because we are born with sin and without God we can do nothing. Not forgiving oneself is an act of pride, it is expecting perfection from ourselves. Don’t compete with others and be compassionate. Don’t pretend to work things out on your own but let God do it.
