I'm the same way: low FoV gives me terrible headaches, like I'm walking around with binoculars strapped to my face. I can go up to 180° very comfortably in minecraft on the other hand. I think the main reason is that the lower the FoV, the faster the image moves when you rotate. If you imagine a comically small 10° for illustration, you will go through 9 full screen wipes if you turn 90°, but if you have 180° of FoV it is only a single ½ wipe. Higher FoV just inherently feels less disorientating to me as well, being able to see all your surroundings makes the virtual space feel more cohesive and real, instead of a series of disconnected whirling imagery.
