Active Baby = Nausea

I have a very active little one. I had to go in for the anatomy scan 3 times because of movements, and my OBGYN refers to it as 'uncooperative' as it moves so much the heart rate is difficult to read. I'm only 27 weeks but can already see distinctive poking...and the baby really comes to life once I lie down for bed. Sleep time for me is party time for him/her. But all this movement is making me feel sick. My appetite is decreasing and I feel nauseous when the movements increase in frequency. Its such a blessing, and I love feeling the movements, but this is the first pregnancy struggle I've had. I escaped morning sickness! Yet this is really beginning to affect me. Has anyone else experienced this or has remedies?
