Not sick until 10 weeks?

I'm 10+3 today! I've been nauseous for weeks now and have been super lucky to not have any vomiting! ...until yesterday. I work at a doctors office and usually get to work around 7:45. I've never been one to eat breakfast (my whole life, not just with pregnancy) and I always feel fine until lunch. Yesterday around 9:30 I started feeling terrible- dizziness, spots in my vision, and a horrible headache. I've never had that happen but figured I needed to eat ASAP so as soon as I got home for lunch at 12:00 I grabbed a yogurt to eat first since it was quick and within minutes realized that wasn't such a good idea. Now I'm afraid of it happening again, so I'm going to try to eat a little something in the mornings in hopes to not get so sick. Just couldn't believe I haven't gotten sick this whole time and it finally hit at 10 weeks! Anyone else experience this?
