What do you eat when you have morning sickness?

soda biscuit plain bread with blueberry jam cooked food that is left to cool down and air (not warm and less smell) mcd fillet burger n fries sushi but non raw toppings 4 mouth of fried rice packet green tea sour plum or fruit juice doesnt work for me..especially when i cannot eat much (too much digestive juice causing more nausea)
