Severance offer, what should I ask for? - what worked for you?

I was offered 10 weeks of severance after 10 years as a web developer, and I have a few days to sign. I do not usually post, so bear with me. It includes health coverage for a couple of months. What did you ask for?

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.
