Im a med-surge RN thinking it was a good place to start my nursing career...But it did me more harm than good because of my negative experience, I almost gave up being a nurse and shifting careers even if they double my salary I never want to work in MS again

. Then I was advised to transfer and find my niche in nursing...after researching, I think I want to become a GI nurse in an ambulatory surgery center even if they say the pay is somewhat less.. the work hours are soooo much better, it's challenging but not the kind of craziness in the floors. I also feel like I dont wanna work in a big hospital. So to all the GI nurses, would please give me tips on how to become like you? My dream now is to be a GI nurse.
1. What are the minimum requirements when I apply to be a GI nurse? Do they accept new grads or with minimal clinical experience in med surge? Is there a cetification for this specialty? Do they prefer applicants with background in surgery/OR nurses?
2. What skill do I need to be good at... starting IV's?
3. Just so i wont be disillusioned like what happened to me as an MS nurse - can you please tell me honestly the pro's and real cons about being a GI nurse?
