Thanks for writing your query.
The cause of your dizziness
seems to be in your ear. The most common cause is Meniere's disease.
You should avoid excess intake of coffee and salt as it is observed that this may increase the discomfort.
You should get yourself examined by an ENT specialist
16 mg thrice a day will be helpful in relief from dizziness.
Also get your head scannned to rule out other causes of dizziness.
I hope this is helpful to you.
