My nausea has shifted a bit...

Amanda
So I threw up a bunch last night and I threw up again just now (almost 5:30 in the evening here). 
My sickness used to be 1st thing in the morning, which wasn't so bad because I could at least keep food down since I would throw up mostly water and whatever crackers I ate to get out of bed. Now I am throwing up everything I ate in the day pretty much. 
Has anyone else experienced a shift in nausea patterns? I am 8 weeks 4 days.
