I ended up on meds. It's called diclegis and it's strictly for pregnancy unlike zofran. It was a life saver.
I had severe morning sickness and vomiting starting at 5weeks all the way to my 23rd week. I threw up about five times in a day and ended up in the hospital twice because I was severely dehydrated. Try to drink as much water as you can but don't drink lots of water at once because if not you will probably end up throwing up the water. Try gatorade, ginger ale, crackers, jello, chicken noodle soup, 7up or sprite, popsicles helped me a lot. Even though my stomach hurt a lot for all the vomiting I forced myself to eat so I could get at least something in but I pretty much ended up throwing up everything I ate by that time. I'm 38weeks and 4days and I'm happy those days are over.
Preggo Drops from Motherhood helped me alot especially when I got car sick which was all the time. It's just hard candy that's like 4 dollars.
