If you are new to pole the dizziness & nausea subsides with time and more practice. A good thing to do is a spin, then pose, pole hold move, spin, then floorwork, spin, dancy dancy, spin. You get the picture...basically do a spin, then do other filler moves, then do another spin, then filler moves this helps gain your equalibirum back/recover between spins. After a few weeks poling, the dizziness will subside greatly. If it doesn't, I know some girls use motion sickness bands when they pole or take half a dramamine (less drowsy ones) before poling. They also have these motion sickness drops that you dab behind you ear, which I hear help too.
