cyclic vomiting syndrome
"I was sick with violent to moderate vomiting episodes daily for 5 years, numerous tests and docs with no answer.
Eventually when I ended up on IV fluids at home we tried amitriptyline it was amazing, a life saver literally.
Now 5 years later it has stopped working and I am devastated. I am trying nortryptaline as a change to see if taking a break from amitryptaline will get it to work again.
I was up to 100 mg every night. 
The nortryptaline is not working at all, I am vomiting numerous times a day.

Has anyone else had great success with amitript, and have it stop? What did you do?
Thank you for any insight from other sufferers, it really helps.
My first episodes started about 32 or 33."
