Ray,
Cisplatin can be kind of rough. It is vital that you drink between 2-3 liters of water every day. Cisplatin needs to be flushed from the system both for it's effectiveness and to lower toxicity to other organs, especially the kidneys. If you are vomiting you will also need to replace the fluids you've lost- it's very easy to become dehydrated. Also, if you need hydration try to have it done in infusion rather than the ER. They are much faster in infusion - 1/2 hour in and out. ER can take 4 hours to infuse the same amount because thay are mandated to do a slower drip since they can't monitor you all of the time.

You'll feel better the further you get from the ct infusion then it will start over again when you get your next one. Follow the instructions they gave you very carefully. Ask for some compazine suppositories if you are too sick to swallow anything or keep it down. There are also other antiemetic meds besides Zofran - I would ask for those as well as Zofran loses it effectivity after 3-5 days.

My second Ciplatin treatment was considerably worse and they decided that I wasn't going to get a third due to adverse reactions.

Remember that we all respond differently to treatment and meds and your response may be much better than mine.
