Horrible Morning Sickness 7 w 3 days

Tara
So this is my third child and my first experience with morning sickness. It lasts from the moment I wake till the moment I go to bed. I take all my prenatal vitamins, I take diclectin, organic gravol, and still no relief! I heard pineapple juice and pickle juice works wonders so I'm trying this now as well. Anyone else have really bad morning sickness? What helped? I read somewhere morning sickness is caused by the lack of b6. I'm getting this but maybe not enough? I may be carrying twins so that could be it? Help please!
