Offer arrived, can I still ask for more? (Toledo)

It is the first offer in 9 months and I do not want to mess it up. I would rather hear the honest version than the polite one. I have a competing interview next week. Did you negotiate?

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.

Keep everything in writing and save the confirmation numbers. It saved me later.
