Morning sickness, does it end?

Elizabeth • Mommy of one beautiful girl, and twin boys (:
Will the morning sickness give me a break? Did it ease up for any of you ladies? And when did it, if it ever did. I'm going on 13 weeks, and it's getting worse and worse. I'm losing weight because of this crap. I was reading that multiple pregnancy, morning sickness last longer, I just want an idea lol.
