At first I found 2C-E to be uncomfortable, but once I built a relationship with it, It was just all pleasant rushes. Mind you, it's still gives me a "body load", i just don't find it unpleasant. I still feel as though there is energy in my solar plexus area, and I could see how if I wasn't in a good set or setting, that it could turn into nausea, especially with higher doses. If I get cold on 2C-E, my muscles get especially jittery, but when my body temp is up it's quite nice. I lose a bit of fine motor control on it too becuase of the jittery aspect. It also makes it slighltly hard to urinate, and it feels a bit dehydrating, but it's nothing like a heavy night of drinking.
But onto CEVs, i never got tooo much in the way of closed eye visuals from 2C-E until one of my more recent trips. I told my friend I didn't get too many CEVs from it, to which he replied "maybe you're not looking properly", and then for the rest of the night when I shut my eyes, every thought I had seemed as though it was part of a huge fractal. As I thought, I would "fall through" the fractals, exposing it's infinite nature. They had a 3D quality to them, and I could kind of control how fast I was falling into the fractal structure, and which part of the fractal design I would fall into. Then later we were listening to some extremely heavy duty intense psy trance, and i had images of two black snake like dragons that were rotating around this hexagon shape, and the whole snakey-hexagon thing was traveling at a super fast pace through a dark void. Very trippy.
