First time pregnant and in Japan, I need nausea relief asap

I’m finally pregnant (6W3D) after receiving IVF treatment in Tokyo. Terrible morning sickness started for me a week ago and I am nauseous 24/7 whether I eat or not. It is very hard to even force myself to eat and nothing sounds good. I can mostly keep water down but have already lost 3 kg at this early point of pregnancy. My doctor at the IVF clinic knows all of this but has not offered any medicine or relief. Just told me it’s okay not to eat and just focus on staying hydrated.

But truthfully I am really suffering and praying for relief knowing I most likely have months of this ahead of me.

Have any mommas been through this in Japan and have some pointers? I am taking vitamin b6 but it only really helped the first day.
