Zofran and constipation

Hi! Never posted and a little horrified that this is my first but I’m desperate. I can’t keep anything down including liquids without Zofran but I’m about to hit two weeks this coming Tuesday without having a movement.

I’ve tried miralax and threw that up, the laxative chews and also vomited that. I tried a suppository today with no luck. What do you do when you’re this constipated and can’t stop taking zofran???
