Did any of the women in your family suffer from morning sickness? That might give you some idea of what to expect. I didn't have morning sickness, but there were a couple of v*ing incidents due to digestive issues.
Personally, I thought it was worth the risk, despite the emet. I didn't want to reach menopause and regret not having children just because I was scared to v*.
Dealing with sick children is scary too, but it's amazing what you can cope with when it's your own child.
Good luck with whatever you decide.
