When I first took flying lessons, I used to get like this to the point of it being a distraction and hence hindering my progress. It can take a few lessons to get over this, but when you do, it is a real sense of achievement.
I used to be absolutely terrified of the stalling/incipient spin exercise before I done it. Once I overcome the "queasy" stage, my instructor at the time took me through the stall and I was happy.
My previous instructor (I had to stop due to financial reasons) took me through the stall and incipient spin, and I found that I really enjoyed the exercise. When you watch it on Flight Sim 2002, it does look horrifying, but when I was in the plane, I found it extremely fun. Oddly enough, I am willing to do these things in an aeroplane, but I still will never go on a rollercoaster.
One flying instructor told me he had a student who threw up 5 minutes into his first lesson, and kept doing this on each lesson. As the lessons went by, it took longer and longer for him to throw up, and then he was cured. He eventually went on to get his PPL.
