nauseated and...

Hi Everyone!!! Last night I had the urge to vomit I felt nauseated and had to vomit at 3:a.m. Had anybody feel this? the need to vomit and if so do you know why? The only thing that comes to my mind is because of the anesthisia. I will check with my Dr. Just wanted to share this and see if any of you had the same. Also my hair is falling off like the water from Niagara Falls!!!! Thank you Millie
