I can't avoid the thought "what if I hate working in an ICU and gave up my good day shift schedule ..."
So, I don't have any experience in adult ICU or tele, however...
As others have pointed out, as with any specialty, be prepared to feel like a new grad again. Be prepared to feel frustrated, overwhelmed, and incompetent at times when you start out. There will probably be days where you think to yourself, "I feel like such a moron as a new ICU nurse, why did I give up my good day shift job?" Just like a new grad, you'll get through it, push past the steep learning curve, and eventually feel like a confident, competent ICU nurse. However, you should mentally prepare yourself to have days where you second-guess your decision, and realize that's ok.
I'm curious to know why you decided to apply? Was there something you hoped to gain from an ICU job that you don't currently have? Knowing more about what you actually enjoy (i.e. pace, acuity, control) would probably help other members give you more helpful insight about what you would or wouldn't like in the ICU setting. IMHO, there's way more to this equation than day shift vs. night shift.
