Ive had norrvo virus when should i start to feel better.

A few days: if you have norovirus, it can last 3-5 days. Depending on how dehydrated you get, it can take a few more days after that to feel normal. Drink a lot to stay hydrated, and add electrolytes and food if you can.

Usually it's: A virus that runs a rather rapid course of clinical symptoms, on the order of two to three days. But this can be quite variable. And you could have linger symptoms that last much longer.
