I’m working on this too

I removed my debit card info from any shopping sites. So I’d have to go out of my way to get up and get up and go across the room to get my wallet out and re-enter all my card info which I’m unlikely to do because I’m lazy so it creates some resistance to spending randomly if you spend a lot online. Other than that as far as spending in stores in person take the amount of cash you need out first and leave your cards at home. You’re less likely to spend too much if you have a set amount and you see the money decreasing physically
