Anyone have good ideas to get rid of morning sickness? Ive tried a lot of things.?

I am on my 3rd kid and i am always tired and always sick. My stomach churns all day and it's hard for me to work full time and then come home to my family and have any energy to do anything but sleep cause i dont feel well. I have tried saltines in the morning, cinnamon capsuls. I have yet to try ginger ale, or ginger snaps, or ginger tea. Any ideas will help. My first kid i had no problem getting rid of it, my second kid.i tried everything i was told and nothing worked. Just want ideas. Thanks!
