Sea bands for morning sickness

E
This is from a former sceptic, but my morning sickness has been getting worse and worse to the point that I was willing to try anything. 
Yesterday I bought sea bands which are supposed to help with motion sickness. They're like tiny fabric cuffs you wear on each wrist and they press into your wrist in a certain place (I think it's an acupressure thing) 
After having them on for about an hour, I got SO HUNGRY. 
I've got to say, my morning sickness hasn't completely gone, but it's MUCH better so far. If anyone is suffering, try them. They're pretty cheap and it's helped me a lot so far.
