Zofran
"This drug has saved my sanity.  I was undiagnosed with a debilitating vomiting sickness.  In hospital at least once a week via ambulance.  Repetitive vomiting and could not stop.  To the point where I would become unresponsive.  After about a month into my undiagnosed sickness, at the emergency room, a nurse gave me a wafer of Zofran.  It was a huuuuge relief as my uncontrollable vomiting stopped within 10 minutes.  I had not heard of the drug but after finally been diagnosed, after 6 months, as having Severe Idiopathic Gastroparesis I found my new best friend.  As well as having a kidney transplant and taking a bucket full of anti-rejection meds, I was soooo grateful that some smart cookie out there invented this drug.  Saved my life"
