Sue, I had my first treatment of Cisplatin on Nov 5. Once I stopped the anti nausea meds it came back. I had a horrible weekend. On Monday, Nov 12 I actually vomited and thought ok this is enough I should be past this by now. They now have me taking Ativan regularly and it works! I can eat and drink now and do not feel nauseous. It is in the Valium family so until he gets used to it, he will feel sleepy. My new problem is the soreness deep in my throat. Hope he does better soon!
