cyclic vomiting syndrome
"We find this medication one of our lifesavers.  My son began Cyclic vomiting syndrome when he was 5 years old. Started out with a bang and he would spend one week per month in the hospital for over a year and a half. We did finally resort to both a G and J Tube. One for nutrition and one to bypass the stomach during episodes to give medicines, fluids and nutrition. However, we use the Elavil every night and use Ativan as well as Zofran during an active cycle or right when we see one coming on to abort as well as loads of fluids.
We have tried to experiment and "see" what happens without the Elavil and it was bad. Within a week of not having it, right on the money comes an active Episode. My son is now 13, we still have the Tubes in place and use all the medicines listed."
