You could ask your dr for some stematil tablets, they are quite good, although they dont work for everyone, i get vertigo very bad, and it leaves me in bed for months, at times, and it really annoys me when people think its 'just a dizzy ’ feeling, you feel like you are dying when its that bad,
my neuro physio has suggested i try some special excercises when it gets really bad, but i am scared of trying them , becuase they make the vertigo worse to begin with.
