All four of mine were impacted as well and I was put to sleep for it. That was like ten years ago when my emet was not AS bad. So basically at that time I didnt know about anti emetics they can give you so I didn't get anything. I think I got some for the pain meds but that was it. I woke up and had horrible heartburn but that was it.
I didn't have n* nor did I v*... I actually was pretty hungry by the time I got home...
I am sure you will be ok.. ask if they can give you an anti emetic! it helps wonders...
good luck!
