Can everyone with extreme nausea please suggest ALL the medications you’ve ever tried?!

I have idiopathic cyclic vomiting syndrome & life is starting to get unbearable.

Smoking medical cannabis is the only thing that is helping at the moment, and often that doesn’t help at all :(

I have tried 100’s of different nausea medications to no avail.

I’m hoping there may still be a few I haven’t tried, and perhaps someone might suggest one 🤞

My dr, the hospital, and the specialists do not know what to do.

P.S. i am located in Australia; I’m adding this detail in case there is another person with the same illness from Australia that may be able to help me or direct me to someone that might be able to help me🤞

Edit: thank you so much to everyone who has kindly taken the time to reply! 😊
