Really tired of this vertigo

Went and saw Dr David Levin on Monday.  A young doc with the latest info.  Introduced me to a drug called betahistine.  It acts to dilate the vasculature around the middle ear and increase flow of the endolymph.  He gave me information but didn't give me a script.   Put me on prednisone 3x a day for a week.      My Diamox prescription went up to $125 a month.  He switched me to HCTZ but said that Diamox is the standard treatment for Meniere's.   I looked into Canadian pharmacies on-line and found that I could get 100 for $55.  

Had one good day Tuesday without symptoms.
Yesterday was Wednesday and I had the onset of vertigo around 1pm.  Sweats and gait disturbance.
The symptoms intensified and I took a meclizine around 2:30.   That gave me some relief for a while but driving home, the vertigo returned.  I had to stop and rest for a bit and then proceeded.  Just about a mile from home, I had a sudden a sudden nausea attack and had to pull over to barf on the side of the road.  Went to bed for two hours then felt better.

Today is Thursday, 2/12/15.   Working at my desk and had another sudden onset of symptoms.  Vertigo & sweats. No nausea yet.  

I'm frustrated with this.   It is effecting the quality of my life and ability to work.   I need relief.
