Morning sickness

Hey guys so I'm 6 weeks and 2 days and my morning sickness is horrible! I have only been able to eat ginger snaps, water and some plain mashed potatoes since late Thursday and it's been a week. Doc said to try the generic unisom/vit b combo and I did,  but that didn't help. my ob is reluctant to give me anti nausea meds. I pray she does bc man working in a pharmacy doing the job of  what we do makes me even more nauseous and made me even vomit at work a few times . My tummy is constantly churning...I hate this morning sickness but I know it will be worth it in the end. :)But it can stop now please!!! Yuck! Any body have any tips? I'd try anything to get through the day
