The only thing i don't like about this virus in particular is that any immunity you build up against it from fighting the virus in your body is not permanent in the long term, so sooner or later your imune system will become just as vunerable to it as you were in the past to it etc.
Eat a healthy diet full of fresh fruit and veg and your body will become stronger at fighting off viruses like this though, for example you need vitamin C (which unfortuatenately your body cannot store, so you need to consume foods with vit C in them everyday- vitamin C is destroyed by heat though so the best way to get it in your diet is to eat fresh raw fruit etc) to make white blood cells which are obviously essential in your body for helping fight off diseases and virus etc
.
Also just keeping up good hygiene is good, the norovirus can be picked from infected surfaces you touch, so lots of washing of hands and stuff is good to help prevent you getting stuff like this

Thankfully though the norovirus isn't that long lasting.
The most nightmarish illness i ever got was glandular fever when i was a teenager- severe stomache pains and migraines, fever and cold sweats, vomiting and constant feeling of sickness, extreme lack of energy/tiredness etc- it went on for many weeks and took months for me to really properly recover (i lost like half a stone in just the first 2 weeks, which wasn't good considering i was already quite underweight at that point in my life), during the worst phases of the symptoms i really thought i was dying (had that feeling of impending doom) it was that bad, i remember praying to god and saying to him something along the lines of "if you've decided i'm going to die, please kill me quickly and so put me out of my misery" lol.
But yeah, i recovered from it eventually- it did do me some liver damage back then since i was anemic at the time as well (i recovered from the damage it did to my liver after about 6months though). Some people don't get that bad a symptoms in reaction to glandular fever, but for some people their imune systems react very badly to the virus and it is a hellish sickness to go through.
Food poisening was pretty bad as well....Anyhoo. If i ever get this "norovirus", i know its gonna suck, but i've been through some really nightmarish sickness already in the past and this norovirus doesn't sound like the worst of them, so i know i should be able to deal with it well enough
