These include laying still in a dark room if you feel very dizzy, drinking plenty of water if you’re being sick and trying to avoid noise and bright lights.
Getting enough sleep, starting to go for walks outside as soon as possible, and when you’re out and about, keeping your eyes focused on a fixed object can also help.
You should avoid driving, cycling or use tools or machinery if you feel dizzy.
Also avoid drinking alcohol as it can make symptoms worse.
