I know this mite sound funny, but are you keeping your head level with the horizon if so you are causing the fluids in your ear to swish around. If you also have a cold it mite be causing it. Try just keep your head straight or tilt it slightly into the turn it mite help a bit. I think it happens to most people at first but you will get used to it. I dont think you need to do the whole Airforce breathing routine it should be no more than 2-3 Gs max
