new job blues....

First let me say I am grateful to have a job and I enjoy being a nurse (most days ). That being said I started working in an ICU a few months ago, completed orientation successfully... but I'm not sure I like my new job. I used to work in an IMC (for 4 years) and was really good at it. Now I feel, well, less than confident. The ICU seems really lonely, everyone does their own thing....or sits on facebook. I'm used to a really hectic floor where everyone helps each other out all the time. Not sure if the ICU is not a great fit for me, if it's just the unit I'm on, or maybe I need to give things more time. Has anyone gone though anything similar while changing jobs? Any words of wisdom would be greatly appreciated.
I'd give it a bit more time, how long does company policy say you have to stay before you can bid on another position? I'd stay until I could bid out.

Thanks for your answer. Not sure how long I have to bid for another position, I think it would be up to my new boss. I don't feel pressured to decide right now, things just haven't seemed to "click" yet.

I heard from an ICU nurse that she did not like her job at first but now she loves it.

More than anything I guess I was just curious to hear about other nurses' experiences of transitioning to a new unit.
