I can't remember the last time I used my debit card ...except for getting cash out of the ATM.
I budget a certain amount of money for food/gas/household items - and get that cash out of the ATM every two weeks. I keep within that amount. For me, it's easier to track and stay within that budget. I also keep some cash in the house for emergencies (not terribly comfortable with that but it is locked up).
Larger purchases, regular bills, etc. are paid with a credit card for the points. If we choose to splurge on an expensive dinner - I'll use it then as well.
I'm old.
