Is it normal to not vomit for five years?
Yep.Totally normal
Yes. Going five years without vomiting is completely normal; plenty of people go much longer without throwing up.
Vomiting isn’t something your body needs to do on a schedule. Some people go years without it, especially if they haven’t had a stomach bug, food poisoning, or another trigger.
By itself, not vomiting for five years isn’t a reason to worry. If you’re asking because you currently feel very sick or can’t vomit despite severe nausea or pain, that’s a different situation and may be worth getting checked.
