You can change the field of view apparently. I don't know if that would help with the sickness? I don't get actual motion sickness but I do feel uneasy when the 'FOV' is too small because it feels like I'm too close to everything and it kind of fries my brain sometimes. But when I set it to about 100 or so, that usually helps.
I haven't played the game very much yet so far. I need motivation. I kinda like the Elder Scrolls games but I just wish they put more effort in to the combat. The few hours I played was as a mage and I won every fight by just holding mouse button 1 to spray everything with fire

I spray for 3 seconds and everything in front of me died, and then 3 seconds later my mana had regenerated.. Hardly the kind of depth I like in an rpg

I might re-start as a Ranger/Archer type because sneaking up on stuff and using the bow seems a bit more fun.
I am playing through the original Dragon Age Origins again. I quite like that game. I'll play Skyrim properly when I've finished, and hopefully there will be another patch by then.
