really? I guess it is true that people are different. I don't suffer from nausea or vomiting or fever but I do wake up with headaches almost every morning and after ive been up for a while they do go away. The part of the shunt in my neck and chest hurt to the point where it is just annoying. My friend even said its sticking out more under the skin so it is more noticible. I don't know what to make of that but what I do know is that I notice it more now then I did years ago.
