Get it checked
If your dizziness
is brought on by a certain movement (turning in bed), then it may be bppv and the epley may be indicated.
Bppv is usually short lived... 6 weeks to several months. If your dizziness is chronic... It should be checked and i would avoid using vestibular suppressants, they will hinder your body's recovery. See your local ENT if you have had this a while.
