Man, I was mad tense the entire time. My whole body was flexed and the nurses kept saying 'calm down you're gonna be fine!'. Did you take any valium beforehand? I remember they gave me one valium and since i'm a relatively big guy I immediately thought 'this isn't going to do anything' and it just put me more on edge. When they put the clamps on my eyes I was at an all-time freakout point. It felt too much like the scene from Clockwork Orange when they're forcing him to watch rapes/nazi stuff.
