Seafood Lunch Illness Strikes - MacKenzie Street, Melbourne Victoria

Melbourne, Victoria, Australia

I attended a birthday lunch here yesterday at 12.45
I did not eat before and did not eat anything after. I ate cold seafood starters and main meals and dessert.
At 10pm I started to get a sore stomach, I went to bed with a heat pack and woke up at 1am. My stomach was churning, I had projectile vomit 4times. I was shaking and shivering, I then went on to vomit every hour, then at 4am diarrhoea started very watery and sore.
I am an absolute mess, it must be food poisoning, I cannot even keep water down. I am still vomiting this morning.
