How often does MAV just show as Dizziness?

I have had what was dx as “classic Migraines” starting at the age of 18
They were pretty consistent until I hit my 30’s

I am now 56 and have had a handful in the last 20+ years BUTTTTT I have had episodes of vertigo (dx with BPPV) and off balanced feeling off and on.
6 months ago I came off Zoloft (15yrs use) and since then I am having daily woozy/dizzy/off balanced/ walking like a drunk.
I also get pressure behind my eyes,nose and forehead.

had MRI and that was “clear” Neurologist thinks this is all migraine.

IF so what can I do? I read “heal your headache” and am going to try the diet…but what else.

I should mention I am on lorazepam daily also (anxiety) and wanted to try to get off that but with my dizziness and whacked head feeling I am scared.

so this may not be the right thread to have posted all this but I definitely am DIZZY.
