Reasons for Simulator Sickness ;

Whenever you play a game, the info you absorb with your eyes is readily processed by your brains, and if your brain evaluates the info wrongly, it sends a message that the info is wrong or 'not the way it wants it to be'.

Causes ;

• Jittery frame or lag
• Insanely fast camera movement
• Too much info to 'digest' in your brain
  (Amount of info too many for the brain to handle. Which means the brain is not catching up to the pace as ran from the computer screen as compared to the eyes, thus causing sickness)

SOLUTIONS ;

1. Playing right. Environment plays a part. Well lit room, so that it doesnt put pressure to your eyes.

2. Stop playing immediately if the problem persists.
(Seriously, the world would not end if you just stop.)

3. Sleep

4. Rest your eyes

MY CONCLUSION ;

Dont play in a dark environment with fake eyelash on your face and wearing your contact lenses out thou you've already worn it the whole damn day, period.

P.S : Im going to play Dark Carnival again to see if it's really that bad
P.P.S : I know the world won't end even if I dont play ;)
