Corsair and MJ both make valid points. Your instructor could be overdoing it abit. Although I'm not going to criticize given that im only a PPL about to start ATPL's!
I know someone else that got queezy doing steep turns and they always found it beneficial to do some nice medium banked turns @ 30 deg then go to 45 deg and move onto the full 60 deg all in one flight. Not sure of the medical reasons why that helped but he said it just eased him into it.
It might help to try and keep yourself busy looking outside for traffic, maintaining the picture throughout the turn and quickly glancing at your instruments to confirm.....god, sorry I sound like a bloody instructor now...im really not but thats a long way of saying try to focus on the job in hand and it may help. Im no expert and I'm sure that's alot easier said than done.
