Making savings last after losing my job - what worked for you?

We are a household of 10 and need to cut costs quickly. I have been trying to stay organised about it. I listed every subscription and found several I forgot.

A simple budget with three columns, fixed, flexible and optional, made decisions faster.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
