Are you taking Zofran (Ondansetron before you take Daraxonrasib? My mom was told to take that 30 minutes before taking the Daraxonrasib. She takes it at night which seemed to help. She can also take it when feeling nauseous and it works quickly.
For diarrhea I would talk to your NP about Imodium and if it gets really bad Lomotil. I hope your symptoms subside quickly.
