I can place both palms flat on the floor so I guess I might a bit more bendy than the standard Fred/MAMIL.
But we digress....
I do the same, which is mostly why this concerns me. If I didn't ride in the drops the majority of a ride I wouldn't be as worried. For me it's honestly more comfortable. I have a strong core, both front and back, and I am very flexible. My core is from when I used to weight lift semi-competitively and my flexibility is a super power I was born with and have never had to work at. I find sitting more up right hurts my hands more in longer rides, so I've just decided drops for the win.
A little update. Went for a ride today. I tried to replicate this, and while I could, I found that by lowering my shoulders closer to the bar and sort of extending my neck forward, rather than just bending it up, I eliminated all dizziness problems. So perhaps it is just posture, which is really good because it may take me a few months to see a doc., apparently it's very difficult to get a physical when you don't have a primary care doc...
