Stephanie Horner suffers from a rare condition that means she throws up 350 times a week.
She has Cyclical Vomiting Syndrome, a little understood illness that causes her to vomit every 20 minutes, playing havoc with her life.
She struggles to hold down a job and had to leave university because of it.
CVS affects one in 300,000 children, with only 20% of adults continuing to have it in later life. To make matters worse doctors are unsure about what causes the illness, and what the best way to treat it is.
She told The Mirror:
It can be a very embarrassing condition because I end up throwing up on myself countless times without any warning from my body.
Every morning I lie in the bath and work out whether I can deal with the condition myself or whether I need medical attention at the hospital. If I misjudge it I could die of dehydration.
She manages her condition by taking 6 drugs a day, and she starts her day with a hot bath to help sooth the pain.
That sounds awful, hopefully someone will work out a way to treat CVS soon! We wish Stephanie all the best.
