MORNING SICKNESS HELP PLZ???

Brittany
So I have had ALL DAY nausea from 4 weeks till now at 6 weeks and I can not hold any food down or liquids! I was perscribed Zofran for the nausea and I do feel it kind of helps but on the other hand I feel my heart races a bit... Anyone have any other cures for the morning sockness besides ginger, crackers, etc....? PLEASE HELP ;)
