Can't remember with my first as that was 7yrs ago, i remember with my 2nd i asked at ob first visit which was around 8wks when i should stop feeling so s...t he said maybe around 12 - 14wks and it lasted till 14 wks. with my 3rd it hit me bang on at 6wks whilst playing volleyball - lasted till around 14wks - i found butterscotch lollies or minties on constant supply to help

good luck
