Suggest Medication For Frequent Headaches And Dizziness Due To Vertigo

I thought I have "Benign Positional Vertigo" as doctors mentioned, medication and physiotherapy did not work for me. Every day my dizziness and headache starts around 9 am and in with me thw whole day and night untill bed time.Today is Saturday, I did nothing untill 1pm and had no issues and no dizziness, at 1pm I checked my e-mails for not more than 10 minutes and noticed that headache and dizziness all started. My problem is that I can't have any income without use of computer and this problem that started early in December with vertigo and vomiting and was told that is related with inner ear is seriously affecting my life. Please advise what should I do
