morning sickness

Keilee
So I've been hit with morning sickness but really bad morning sickness to the point it's lasting all day. I can't keep anything down not even water, I've been prescribed anti sickness tablets from my doctor but I'm so apprehensive about taking them. 
I suffered 2 miscarriages last year quite close together and I want to do anything and everything to prevent another one.
Just looking for a reassurance out there!
