Timely topic for me as the ringing in my ears started back in November with a bout of what you are describing, weasel.
Doc gave me the same meds; I only had the projectile vomiting for a day and the dizziness went away after a couple of days.
Finally got fed up the 1st of this month and my doc referred me to the audiologists. They put me through a battery of tests, including an MRI of my head and bloodwork.
They didn't find anything and I'm going back to the audiologists next week to begin trying some hearing aids to see if they will help any. I hope they do; the ringing isn't debilitating, but its very annoying at times.
The 1st thing the audiologist told me when I met him is that not much is known about tinnitus and there is no known cure for it....:shrug:
i feel your pain,brother......g.l. with getting well...
