Two days in a row this game has given me a serious headache, it hasn't been a problem because i've some left over Vicodan from a recent trip to the dentist, but it's still pretty bothersome. 
 I think it's the close camera angle and the constant 180 degree turns. Does anyone else have this problem with any other game?

You might look at taking a break from playing video games if you are getting consistent headaches. Sometimes being in front of a television or monitor for too long hurts my eyes, which, in turn, causes headaches that grow increasingly more irritating over time.  
 
Just take a nap or something in your free time. Chill and listen to music. 

Maybe it's the bloom?
