Anyone else have morning sickness BAD!?

Cass
I am 7 weeks. Due end Feb. m/s started last week but has gotten so bad that I ended up in hospital with dehydration. Can't even keep down water without zofran/ondansatron. When it wears off I'm ill again. 
​Is anyone else suffering badly? If so how long did it last for? Any tips for managing it? Did u take medication and if so what and did everything work out ok?
