nausea/vomiting
"Experiencing horrible nausea/vomiting with Dilaudid for pain associated with Stage4 Breast cancer. My normal antinausea medication was Zofran, but it started to not work. I was given 0.5 mg I.V. of Haldol every hour for nausea. It worked, but did "knock me to nap" for a little while. After I woke up, I did feel groggy and was able to eat and drink without incident."
