Lorazepam
"Lorazepam is the only thing that touches my nausea after having chemotherapy and for break-through nausea from the chemo.  I was not aware that this was a medicine used for nausea until my Dr. prescribed them for me and told me to dissolve them under my tongue for the nausea.  It almost always helps immediately and doesn't make me too drowsy to function. I just use 1mg. dosage and only when needed for the nausea and that is improving so I am very thankful."
