Morning sickness has gotten the best of me :/

I've been sick from pretty much the day I took a hpt and even a bit before that! I'm 12weeks and still so sick they have put me on so many different medications to help with the puking but so far nothing really helps they have me on iv of zafron twice a day it's help a bit but what I want to know is how many of you ladies had it this bad what helped and how long did your morning sickness last I'm hoping not much longer!
