Baby moving so much - it's making me feel sick

Lily • 💕20 and pregnant with our first baby! I'm a bit of a princess at times💕
My boy started moving like mad today, kicking, rolling and stretching out. It was fine, but it's gotten more intense during the day and it's making me feel sick. My stomach hurts a bit and I know that if I have dinner now it won't settle and him moving around so much may make me sick.
 
I love having him move this much, especially at 20-ish weeks, but is there anything I can do? 
 
I can hardly stop going to the bathroom long enough to make myself some dinner, I'm exhausted. Can I settle him in any way??
