Does anyone know if the CGRP drugs also relieve the nausea, vomiting, and diarrhea associated with gastroparesis related to chronic migraine? Basically, I’m wondering if I respond well to the CGRP (fingers crossed), will I then need to continue treating the nausea and vomiting or will it get better as well? Can’t seem to find any information about that. I have 25 attacks a month on average, but the nausea and vomiting are constant. I haven’t had a day without nausea in a year and I vomit at least one day a week. I used to have to go to the ER to get IV fluids and IV phenergan at least once a month, but I’ve gotten better about oral rehydration and treating the nausea (one way or another) before I vomit myself into dehydration.
