Severance offer, what should I ask for? - any advice?

I was offered 9 weeks of severance after 9 years as a store manager, and I have a few days to sign. I worked as a store manager before this. There is a non-disparagement clause. What did you ask for?

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