I read on here, and anecdotes from friends that hardly ever seem to get a vomiting bug but I've been off again today with one. Feel absolutely dreadful. Woke up in the night with stomach ache and then a few hours later it started. I only had the last one in December. I do work with small children as a Reception teacher but I thought my immune system would have developed by now. I feel terrible being off again today, especially as it always seems to be the same thing. Anyone got any top tips to boost my immunity? I am quite obsessed about hand washing anyway!
