How much room is there after an offer? - first time posting

It is the first offer in 2 months and I do not want to mess it up. I do not usually post, so bear with me. The benefits are decent. Did you negotiate?

Most employers expect a short conversation. Mine did not even blink.

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.
