Been doing this for many years. If something that unexpectedly gets charged, I know right away or I just goes away. This way I have to some degree regained control.
I wanted to do this as well, but it honestly takes so much time to change payment details on a lot of services. All my utilities for example are on auto payment through my credit card, I need to go to a physical store to change that. It's one of the reasons I haven't cancelled one of my credit cards, even though I haven't used it in years.
