Morning sickness question.

I have been so sick these last couple days, it’s been hitting me hard. Everything I have been eating and drinking been just coming out both ends sorry tmi I know. I’m getting some medicine prescribed and sent to my house tomorrow but question is what can I do or eat or drink that will help till I get the medicine? I’m hoping the medicine works cause I’m only 6weeks and 1 day pregnant and it’s killing me. I have four children to attend to on a daily basis and I’m curl in a ball in my bed as soon as my husband comes home. I’m throwing up throughout the day while with my kids. So any help please.?
