I remember my own spin training here in Canada. I had the same experience as you: eight spins in a row left me feeling nauseous. Best to limit this (important) training to, say, four or five spins at a time, otherwise the educational value begins to diminish!
BTW, Transport Canada deleted spins from the PPL flight test in 1999 (not without considerable opposition in some quarters). They do remain part of the training syllabus, as you say. Do UK pilots receive no training in fully developed spins?
Hard to believe!
