Hmm. A proper steep turn = 60 degrees = 2G. No more. You do NOT need to be doing G straining at 2g. I'm not sure it's physiologically possible to be experiencing vision efects at that level. You also should be looking around for other traffic, so keeping the head still is not really an option..
I suspect it's a case of 'get used to it'. for my money you will - my first stall scared me, my first spin ditto..
If not Diamond dog might have a point.
