How to help morning sickness?

I’m 13 weeks pregnant with Twins and sick ALL the time. Everything makes me nauseous including Ginger, Lemons, bland foods, healthy foods, there is literally nothing I can eat where I don’t feel miserable for hours. I have heard that inhumane nausea is common with twin pregnancies. My question is for other mommas with twins, when did you start feeling better ?! please tell me it gets better soon!!!
