You don't need to have the physical urge or cramping to feel nauseated. In fact, for alot of people, it's just more of a queezy feeling and can include aversion to certain smells, dizziness and off balance. For several weeks, in fact, I thought I was coming down with an ear infection or something because it felt like I was half-drunk and I'd find myself feeling for walls and chairbacks to make sure I was moving in a forward motion. I got lots of teasing for that. If your nausea continues for a long time or gets progressively worse, you might ask for anti-nausea meds. Most docs will prescribe phenergan, but that often comes w/ drowsiness as a side effect. If you aren't fortunate enough to be able to just lay down and take a nap whenever it hits you, ask your doctor about Zofran. I thought I'd been given a miracle! Could have even passed a field sobriety test once I had that stuff in me.
