30 years without correct diagnosis and treatment

I had the symptoms of recurrent extreme nausea and vomiting since birth. I had years were I vomiting 26 weeks of the year, for days at one time! No doctor found the cause so it was thought "psychosomatic" for 30 years, no treatment worked. Than a family friend found about Cyclic Vomiting Syndrome, all symptoms fitted 100% so I did research the standard treatment for that and it worked! Since then I have control over this illness.
