Severance offer, what should I ask for?

I was offered 10 weeks of severance after 10 years as a janitorial supervisor, and I have a few days to sign. It includes health coverage for a couple of months. Did anyone negotiate and succeed?

Read the release carefully. Mine included things I did not expect, like a non-compete.

An hour with an employment lawyer cost me a small fee and made me feel much safer about signing.
