Here’s a neat project to try – take a month’s expenses from your budget, and take it out in cash however you like. Take cash out on a weekly, bi-weekly or monthly basis, whatever works for you, and then spend it as usual.
Keep a log, whether paper or on your phone, that logs where and when you spend your cash.
See if this makes a difference in your spending habits for the month. Worth a try to make you more conscious of your spending.
