Hi, I'm completely new to this site and really hoping someone can help. My 8 year od son was diagnosed last year with cyclic vomiting syndrome and I was googling for any new info when I came across this site. My son 'cycles' every 3 weeks with a vomiting episode lasting around 16 hours each time. Are there any Mums out there with children who have this, and if so, have you found anything or been prescribed anything that eases it? Thanks x
