Morning sickness

Emily
How do you cope with morning sickness. 
I have continual nausea throughout the day. 
When I eat certain things feels worse 
Try eating minimal (saltine cracker water Gatorade toast rice so forth) that doesn't help when I eat normal doesn't help. Seem to throw up that way. 
Plus I have a metallic taste and smell which doesn't help. 
Does anything work for you? 
And how long do people feel nausea for. 
I'm currently 9.1 weeks.
