Sour candy helps with nausea

Sara
I am almost 7 weeks pregnant and I have been nauseous just about every day for a week now. We had some sour patch kids in our pantry and jokingly I told my hubby I was going to eat some because it will help my nausea (I just wanted candy). I ate several of them and all of a sudden my nausea was gone! I ended up looking it up to find out it really does help. 
For you ladies that have been feeling nauseous too any sour candy helps as well as lemons. I have been looking up all sorts of stuff lately and for some reason I didn't look up what to eat to help with this.
