Kate is the woman who has it all. She's the perfect Mum, wife and daughter until - for the first time in her charmed life - things do not go to plan. In her second pregnancy, Kate develops extreme morning sickness (hyperemesis gravidarum) and, quite literally, cannot stop vomiting.

So how does all this endless purging, spewing and upchucking (not to mention the non-stop urge to spit into a bucket) change Kate's understanding of her family, her marriage and, ultimately, her own identity? And, of all the visitors to her bedside offering tea, dry toast, and stories from her childhood, who can she really trust?

This funny, dark and joyfully disgusting "vom com" by Annalisa Dinnella takes inspiration from the playwright's own experience of this rare and often misunderstood complication of pregnancy - also made famous by the Duchess of Cambridge. Do not try to eat while listening.
