Nausea relief

I have never posted on a forum such as this one and I'm so excited to finally feel like I have the support of other pregnant mommies! This is my fourth pregnancy. I currently have the IUD and I'm 11 weeks pregnant! My doctor is keeping a close eye on me. However this post is actually about my nausea! It is so unbelievably horrible this time around and my doctor even tried prescribing some medicine but nothing is helping! I vomit at least two times a day if not more even after meals. Has anyone gone through this? Help!!!!!!
