I'm prone to motion sickness but only on certain theme park rides and sometimes car rides. I was nervous trying VR knowing the potential issues. I've tried several apps. None gave me any motion sickness but I did get a minor headache and some eyestrain my first try. Second time those symptoms weren't as bad and I could use it longer. I suggest , like others said, ease into it. Don't push yourself and let your sensory system get accustomed to it. Even when you are, I read that occasional breaks are often needed for most people.
