Started after a chicken pizza takeaway Saturday, vomited from 6am sunday after feeling nauseous all night, lasted till about 930am then has some bouts of diarrhoea. Felt well enough to eat Monday so had toast, stomached that fine so ate some mash for dinner. Then, the dreaded Tuesday morning I was up at 4am in the morning and it started over, vomiting until 9, then diarrhoea every 30mins or less I lost count. Last bout at about 5pm, but decided against trying to eat. It s now Wednesday and I m feeling better, no longer nauseous but I ve had 2 plain biscuits, a packet of baked crisps and a bannana as well as 2 small chocolates and a yogurt drink. I now feel like I m constipated, been trying to go to the toilet all day and had very small dark green stool and every other time just green mucus on the tissue. Is this just my body going back to normal or? I ve taken 2 rennies.
