Hmm, this is a tough one. Have you tried disabling motion blur?

Valve was so nice to make it extremely difficult for you to turn motion blur (the likely suspect) off in Portal 2. This thread of mine contains all you need to know:

Motion blur is a stupid feature anyway, since it works against the natural perception of the brain and tries to outsource/emulate that function onto the screen, which, by nature, cannot work properly and becomes confusing.

I just got the game and I can't play it either because of motion sickness. T.T
This would happen all the time when I played Halo so I ended up not playing it at all. Funny thing is, on wikipedia it says that in a study 50% the people who played Halo felt sick after playing for less than an hour (ofcourse the 50% is limited to the people who were in the study) but I guess lots of people get motion sickness while playing first person shooter type games.

To add onto my previous comment for some games changing the field of view could make it better but I don't think you have the option to do that in portal.

You can change the fov using the 'cl_fov <number>' console command.

I don't get it, but try sitting higher than your moniter. Studies show that helps.
