Ab initio Air Sickness
Don't worry airbus pilot, human beings were not designed to be flying and therefore have to adapt to the "new" environment. Primarily the air sickness is due to just that- therefore u must try keep yourself orientated at all times. Identify places on the ground or momentarily focus on a village/town or river.
Being a QFI I have seen this happening more often when the trainee gets "isolated" from the aircraft due to some primal fear of the unknown. So don't get overawed by flying instead try to make yourself feel that the aircraft is a part of you. Just to inform you that I too used to feel airsick- today I have 4800 hours 3000 on fast jets and 24 years of "you name it, I,ve done it" flying behind me.
Hope it helps
