I didn't have much nausea or vomiting either. Was always able to get my water and protein in once I started on soft foods. Worst problem I had was some faintness after eating - needed to sit down and rest for 20 minutes after eating for about 4-6 months. A year out, and I've made it below my original goal. I couldn't be happier, and am so glad I did it.
Nausea and vomiting is not how this is supposed to work or anything. It's just a common problem. Part of the way that it works is by restricting how much you can eat, and giving you a full feeling faster. But actually, scientists don't entirely understand why it works so well. If they did, they would be trying to find a non-surgical route that achieves the same effect.
And of course, as @Officially Not Fatty Matty said, forums are going to have more of the complaints than the average experience. People usually don't seek out forums so they can post "OMG this is so easy." They seek out forums when they are having issues and need some advice.
