Well I vomited at my office today, so it would appear that I have morning sickness. :\
Thus far I've just been eating mints when I feel sick, since it's usually brought on by smells and mint overpowers them. Pre-pregnancy I had the nose of a bloodhound, so now it's just madness. It's like I can taste everything with a scent... and since I take public transit (including a rather shaky ferry) every morning, it's going to be long couple of months.
I've also noticed that it's worst when I go without eating, so I make a point of eating right away in the morning.
