Should I negotiate my severance? after 3 years as a pharmacy technician

I was offered 3 weeks of severance after 3 years as a pharmacy technician, and I have a few days to sign. There is a non-disparagement clause. What did you ask for?

Thanks for writing this out. I went through something close to it 4 months ago, and it got easier once I kept a simple log of every call and form.
