On Saturday afternoon around 3pm I ate a chicken 6 inch sub with lettuce and cucumber on my lunch break, felt fine all day until I ate the sandwich. Then started feeling dizzy, nauseous and getting stomach aches. After a difficult shift feeling very ill at 7pm I went home and got straight in bed where I started getting hot flushes, sweat out breaks and a high temperature, after hours of discomfort around 2am I was sick and continued to be sick for a further few hours. After I woke up in the morning I was still having hot flushes and had a very high temperature. Throughout Sunday I had been on and off the toilet unable to eat and feeling very sick still.
