Appropriate amount of notice

If you're in a right to work State then you can leave at any time, for any reason just like your employer could terminate you at any time, for any reason. However, doing so looks very, very bad and you can forget using them as a reference or working for the organization in the future.

Better to give the standard two weeks, if you don't have a minimum requirement, as a professional courtesy so as not to burn any bridges.

Thank you, that is what I was thinking.

You do not mention how long you have worked there nor your patient base. Do you see repetitive patients or do you work as a group (first come first serve). This could have a bearing on length of time. If you have your own patient base, and it is extensive, 2 weeks may not be enough time to "spread" your patients throughout the practice.

I have been there for 5 months, and It's a first come first serve basis.

Oh goodness...a walk-in "fast food" pain management clinic. That sounds no fun.

Lol that is exactly what it is!! Never thought of tha before.
