Morning sickness

Haley
I'll be three months in two days with my first, 
I Can't keep ANYTHING down. 
I'm able to keep two or three crackers down and Gatorade. I can't take any Nausea Medicean because of medical reasons..
I'm puking or very nauseous from about 4 in the morning untill 12 in the evening, 
Does anyone have any tips , or anything. That helped them?
