Morning sickness cures

S
I've had the worst morning sickness that just lasts all day. Sometimes I'll be ok with the crackers and water (haven't tried ginger ale yet, don't keep soda in the house) and I'll be fine all day. But then there's days like today when I do the crackers and water and still am nauseous all day. My SO took me out for lunch and I barely touched the food because every bite made me want to puke. For dinner we had McDonald's (I got a Mcchicken and fries) all I could eat we're the fries. I'm craving food all the time. I don't know what to do to curb the sickness though.
