nausea/vomiting
"Was prescribed from the doc at the walk-in Ondanstron for severe vomiting due to food poisoning when I was out the day before, it stopped that but long story short I had to be in the hospital for 3 days to monitor & do tests about my heart as they thought I suffered a silent heart attack after only 3 pills, they won't admit to that drug causing some of what I got though & only that I ingested an acute viral infection. Not fun."
